Summary:

In this talk, recent experimental work on nanofiber mat cathodes and anodes for hydrogen/air fuel cells will be described. Procedures for fabricating high particle-loaded nanofibers containing various Platinum and Platinum-alloy catalysts will be presented. The effects of catalyst type and loading on MEA power output and durability in a hydrogen/air proton exchange membrane fuel cell at high and low relative humidity feed gas conditions will be discussed.
