Electrodes for Polymer Electrolyte Membrane Operation on Hydrogen/Air and Reformate/Air

Approach • Investigate the use of reconfigured anodes to improve fuel cell performance in the presence of trace levels of CO impurities. • Evaluate new anode catalysts for CO tolerance. • Investigate porosity and fuel cell performance as functions of the ionomer content in the catalyst layer. • Evaluate new cathode catalyst materials for higher operating efficiencies at lower precious metal loadings. • Investigate the effect of potential ambient air impurities on cathode performance.
