Abstract:
A small molecule or polymer additive can be used in preparation of a membrane electrode assembly to improve its durability and performance under low relative humidity in a fuel cell. Specifically, a method of forming a membrane electrode assembly comprising a proton exchange membrane, comprises providing an additive comprising at least two nitrogen atoms to the membrane electrode assembly.
