摘要

本文研究了不同降解机制对高温PEM燃料电池电性能的影响。燃料电池成分和内部化学的变化与电性能的下降有关。我们将特别讨论三个主要影响。这包括碳载体和催化剂降解的影响，膜中磷酸的损失和催化剂层的CO中毒。

Degradation of high temperature PEM fuel cells and the impact on electrical performance

This paper presents the effect different degradation mechanisms have on the electrical performance of a high temperature PEM fuel cell. The changes to the fuel cell composition and internal chemistry is related the drop in electrical performance. In particular, three main effects will be discussed. This includes the impact of carbon support and catalyst degradation, loss of phosphoric acid in the membrane and CO poisoning of the catalyst layer.
