Electrocatalysts for High-Efficiency, Solid-Polymer-Electrolyte Fuel Cell (7541-020)

Abstract:

A novel platinum catalyst preparation technique will be applied to develop electrodes
for solid-polymer-electrolyte fuel cells (SPEFC). Previous work has shown that this
novel technique results in high utilization of the platinum. With this technique,
low-platinum-content electrodes have been prepared with equivalent performance to
state-of-the-art SPEFC electrodes containing 80 times more platinum. The objective
of this project is to develop and extend this technique to prepare high platinum
content (i.e., equivalent to state-of-the-art platinum contents) electrodes with
improved efficiency. Such electrodes are critical enabling component technologies
for high efficiency regenerative fuel cells.
Applications could appear in high-efficiency and high-energy-density power systems
for use in submersibles.
