Abstract
For a Polymer electrolyte membrane fuel cell (PEMFC) to be used commercially in stationary or transportation applications, cost and durability are the major challenges. Accordingly, there remains a need in the art to understand the degradation of fuel cell components and to develop design improvements to mitigate or eliminate such degradation. At Ballard, an accelerated stress test (AST) has been developed and used to evaluate the degradation resistance of different cathode catalyst materials and structures. Some cathode catalyst layer designs shown here demonstrated increased resistance to performance degradation due to carbon corrosion and Pt agglomeration/dissolution/migration without compromising performance.
