Electrocatalysts and its application account for the largest portion of PEM fuel cell cost. It is also critically important for the system durability. There has been significant effort in pursuing highly active catalysts and good progress has been made. However, long term stability is a critical challenge. Here we will discuss our understanding of catalyst instability and our approaches to address the instability issues for both precious metal and PGM-free catalysts.
