72714S03-I The Proton Exchange Membrane (PEM) fuel cell uses an electrochemical process to generate electricity with zero emissions and high efficiency. Current state-of-the-art PEM fuel cells, operating at ambient pressure, have a power density of 100milliWatt/cm2 at 0.8V. However, power density enhancements greater than 200% would be required to meet the cost and performance targets for automobile and stationary fuel cell applications. The oxidation-reduction reaction kinetics at the anode and cathode electrodes is a process that could be targeted for improving PEM fuel cell performance. In particular, the oxygen reduction reaction at the cathode needs advanced catalyst structures to improve overall fuel cell performance. This project will develop advanced molecular-sieve-based nano-cathode structures to improve cathode reaction kinetics by reducing mass transfer and ionic resistance losses. Phase I will develop the advanced molecular-sieve-based nano-cathode structures, conduct Microelectrode Array (MEA) fabrication, and evaluate the feasibility of the concept. Commercial Applications and Other Benefits as described by awardee: The technology should reduce the cost of the PEM fuel cell system and accelerate the commercialization of PEM fuel cells for both transportation and stationary applications, resulting in significant fuel savings and cleaner air quality for the nation.
