摘要

Perfluorinated sulfonic acid ionomers are subject to chemical degradation under fuel cell conditions 1. Main product detected in fuel cell water is HF 2. Degradation rate increases with increasing gas crossover 3. Degradation rate increases with presence of Fe(II) (consistent with Fenton's mechanism) 4. Ionomer in catalyst layer may not degrade at the same rate as membrane.
