Abstract

A fuel cell membrane electrode assembly having: a proton exchange membrane, an anode catalyst coating on one side of the membrane, and a cathode catalyst coating on the other side of the membrane. The cathode catalyst coating has at least two carbon catalyst layers, with a low porosity layer adjacent to a high porosity layer. The high porosity layers have a volume fraction that is higher than the volume fraction of the low porosity layers.
