Abstract
Electrospun nanofibrous catalysts made of non-Platinum group metal (non-PGM), low cost precursors are studied for the ORR to be applied in a PEM fuel cell cathode. Optimizing the structure of proton exchange membrane (PEM) fuel cell cathodes is essential to reduce the high cathode loadings (1 to 6 mg of catalyst per cm2), used for non-PGM catalysts to compensate for the lower activity against standard Pt catalysts. Electrospinning is used to shape the catalytic precursors in a network of nanofibers to study the effect of the electrospun architecture with respect to fuel cell performance.
