LANL wins award for contributions to advancement of fuel cell catalyst development
Each year, the Peer Review Panel at the Annual Merit Review and Peer Evaluation Meeting reviews the hydrogen and fuel cell projects funded by DOE's Hydrogen Program. After evaluating the merit of the 2010 hydrogen and fuel cell projects, the Peer Review Panel recognized Dr. Piotr Zelenay and his team at Los Alamos National Laboratory for their outstanding contribution to the advancement of fuel cell catalyst development. Dr. Zelenay is the Principal Investigator on an advanced cathode catalyst project that recently produced several significant results. He and his team have dramatically improved the performance of non-platinum group metal (non-PGM) catalysts through optimization of synthesis conditions and addition of new precursors. The use of fuel cell catalysts containing non-PGMs could help reduce cost and accelerate commercialization of fuel cells. LANL has achieved a 100-fold improvement in non-PEM catalyst performance since 2008, exceeding the DOE 2010 target of 130 A/cm3 at 0.8 V. Dr. Zelenay and his team have also increased the durability of non-PGM catalysts under fuel cell operating conditions.

LANL Fuel Cell research cited by FreedomCAR and Fuel Partnership for 7th year in a row
For the 7th year in a row, LANL fuel cell research has been cited as a top technical accomplishment by the FreedomCAR and Fuel Partnership. The just-released report summarizes key technical accomplishments achieved in support of the FreedomCAR and Fuel Partnership in 2009. The partnership selected material for the 2009 Highlights of Technical Accomplishments Report from many hundreds of projects. The LANL Fuel Cell team was cited for studying the effects of impurities in both the hydrogen fuel stream and the air stream. Impurities compromise the performance and durability of fuel cells. This work is critical to help set the fuel quality specifications, determine what on-board air purification systems are required and develop in-situ recovery methods for contaminant removal. LANL has focused on the effects of H2S, NH3 and hydrocarbons in the fuel stream and SOx and NOx in the air stream.

High-tech success stories – the next generation
Postdoc fellow aims to create marketable products based on own research

Often there’s a gap between research conducted at the Laboratory and what is needed to turn that research into useful technology. Bart Raeymaekers’ job is to fill that gap, according to Dipen Sinha, Acoustics and Sensors team leader and Raeymaekers’ supervisor.

As the Lab’s first Entrepreneurial Postdoctoral Fellow, Raeymaekers is on a two-year appointment that integrates postdoctoral research with Bartcommercialization endeavors. The Technology Transferdesigned program aims to respond to a trend among students in graduate programs in science to look beyond the conventional career tracks for science doctorates.

“As EP Fellow, Bart can show us that there is a pathway to turning good research into either a product or useful technology that can benefit society,” said Sinha. “He has already identified a couple of projects that can lead to some very interesting biomedical diagnostic instruments, although those projects are meant for completely different applications.”

Raeymaekers, who holds a doctorate in mechanical engineering from the University of California at San Diego and an MBA from the Massachusetts Institute of Technology, came to the United States in 2004 on a fellowship from the Belgian American Educational Foundation. While in business school, he acquired operational experience at a Web 2.0 start-up dealing with online video search and cofounded a start-up that provided quantitative trade-optimization services to institutional investors.

“The combination of a PhD in engineering and an MBA provides me with the educational background to do innovative research, as well as commercialize technology,” Raeymaekers said. “In addition, it allows me to look at a business idea from both a technical and a commercial angle.”

On the job since October, Raeymaekers has come up with new ideas that combine what he’s learned at the Lab with his previous thesis research. “One idea, if it pans out, can have a significant impact on magnetic recording technology,” Sinha said

A former semiprofessional cyclist with 13 peer-reviewed journal papers to his name, Raeymaekers hopes that his research at the Laboratory results in innovations that eventually reach commercialization and generate a revenue stream. “I also want to learn about licensing and intellectual property strategy,” he said. “My goal is to do a start-up company, hopefully with technology that is a result of the research I performed.”

Problem-Solving Ace
The position of “problem solver” is not officially listed on Dipen Sinha’s curriculum vitae, but a quick look at his credentials leaves no doubt that it’s an apt description.

Dipen Sinha - Problem-Solving Ace

The recipient of numerous awards for his sensor work, Sinha of Sensors and Electromechanical Devices (MPA-11) is the principal investigator in two crucial national energy security projects between Chevron Corporation and the Laboratory: noninvasive multiphase flow metering and acoustic reservoir imaging.

“Anyone in any field can come up to me with a technical problem, and if it is challenging enough and fun enough, I want to learn about that new field and solve that problem,” said Sinha. “And I believe every problem has a solution. It may be a difficult solution, but there is a solution.”

This attitude has drawn a diverse set of patrons—from medical doctors to geologists—to Sinha’s door, a situation he finds invigorating. “When they give me a problem to solve, they don’t realize they’ve done me a favor,” he explained.

Some of Sinha’s inventions for industry—Chevron in particular—include a solids flow sensor, which noninvasively detects sand in an oil bore; a device for ultrasonic imaging of particulate matter, which may revolutionize the detection of debris in oil pipelines; and an acoustic flashlight that uses sound waves like a light beam to create images underground (developed in collaboration with Cristian Pantea of MPA-11).

The atmosphere at Los Alamos, unlike that at a university or a company, allows exposure to so many diverse research areas, noted Sinha. “It’s one of the joys of working here,” he said.

Always contemplating more challenges, Sinha said his new fascination is how to mimic nature’s functionality with modern or newly invented materials. “Real-life problems are so incredibly challenging and fun,” he said. “They are very, very hard, but they still must be solved, because people need solutions. If life depends on it, we will come up with a solution.”

Bashyam’s paper was selected by a panel of Laboratory technical staff members, and the research represents a seminal contribution to the field. He will receive a certificate, monetary award, and be given the opportunity to discuss his research at an upcoming Physics/Theoretical Division colloquium this fall.

The Department of Energy’s Office of Hydrogen, Fuel Cells and Infrastructure Technologies funds much of the polymer electrolyte fuel-cell research at Los Alamos.

MPA-11 member receives Distinguished Performance Small Team Award
Dipen Sinha (MPA-11), along with John Russell, Otis Peterson, and Robb Hermes (TT-D), and collaborator Jacobo Archuleta (ISR-4), recently received a Distinguished Performance Small Team Award for the Strategic Alliance for Advanced Energy Solutions between Los Alamos and Chevron Corporation. The team partnered with Chevron Corporation to address critical energy security issues. This partnership led to three significant successes: Swept-Frequency Acoustic Interferometry (SFAI), Trapped Annular Pressure (TAP), and Inficomm.

Sinha is project leader for SFAI, which applies acoustic spectroscopy to several important oil field problems, including diagnostics showing the proportion of oil, gas, sand, and water produced in a well and separation of this stream with noncontact methods and without the use of chemicals; and oil field diagnostics that help locate deposits that are increasingly difficult to find and extract.

The team used TAP to identify a solution for ruptured deep sea well casings when super-heated oil and gas were extracted in near-freezing water. Each rupture cost approximately $100 million per lost well. Inficomm technology, developed for defense customers to secure wireless battlefield communications, revolutionized the oil industry’s ability to map real-time performance of an entire oil field, predict extraction efficiencies, and prioritize sites for new drilling.

Graduating Class of the first LANL Fuel Cell Short Course

Materials Research Highlight
Polymer electrolyte membrane (PEM) fuel cell durability
Energy efficient, clean fuel cells have the potential to replace the vehicle’s internal combustion engine. Specifically, with fast-start capability and low temperature operation, the polymer electrolyte membrane (PEM) fuel cell is the current focus for light-duty vehicles. The durability of fuel cell systems, however, has not been established. To be commercially successful, fuel cell power systems must be as durable and reliable as current automotive engines, i.e., a 5,000 hour lifespan and functionality over a range of vehicle operating conditions (-40° to +40° C ambient temperature). Click here to read about our work.

LANL Fuel Cell Article Most-Downloaded
According to Fuel Cells, a bimonthly publication from Wiley Interscience, the most downloaded article for 2005 was "The Chemical and Structural Nature of Proton Exchange Membrane Fuel Cell Properties," co-authored by Mike Hickner, a former Graduate Research Associate with the Fuel Cell Team (currently on staff at Sandia National Labs) and Brian Pivorar, Team Leader of the LANL Fuel Cell Team. Fuel Cells, lauched in 2001, is the first and only scientific journal encompassing all types of fuel cell research, from fundamental research to applied engineering.

LANL Fuel Cell Work Recognized
Los Alamos research efforts were selected as four of the Top Ten Research Accomplishments in 2005 by the Freedom Cooperative Automotive Research (FreedomCAR) Fuel Cell Technology Team. In addition, two of the remaining selected accomplishments by Oak Ridge National Laboratory and Brookhaven National Laboratory are LANL collaborations. These accomplishments were presented to the directors of FreedomCAR on October 4 in Detroit. The four selected Los Alamos research accomplishments address the key barriers to commercialization of polymer electrolyte membrane (PEM) fuel cells, namely cost and durability. The selected accomplishments recognized LANL's work to identify fundamental mechanisms related to PEM fuel cell durability, the development and testing of non-platinum oxygen reduction catalysts with improved high-current activity, LANL's studies in the effects of subfreezing conditions on PEM fuel cell durability, and LANL's development of a single-cell testing protocol with the U.S. Fuel Cell Council and completion of round-robin testing. These accomplishments were of direct benefit to industry. The presentation to the FreedomCAR directors noted that the LANL demonstration of the affect of reactant humidification on platinum catalyst particle size growth "partially invalidates GM 2004 concern about catalyst durability in high temperature membranes (at low relative humidity)." The first of the two collaborative accomplishments recognized Brookhaven National Laboratory for the BNL/LANL collaboration on low-platinum oxygen reduction catalysts [with LANL-made membrane electrode assemblies (MEAs), using the BNL catalyst]. The second collaborative accomplishment recognized Oak Ridge National Laboratory for the ORNL/LANL collaboration for TEM imaging of new and used fuel cell components.
