Electrode with catalyst segmentation

摘要

A fuel cell assembly includes an anode with a catalyst layer and a gas inlet end, and a cathode with a catalyst layer and a gas inlet end. The assembly comprises a catalyst layer including a first and second set of catalyst segment pairs spaced apart respectively with first and second distances, a first ratio of an average segment width of the first set of catalyst segment pairs relative to the first distance being different from a second ratio of an average segment width of the second set of catalyst segment pairs relative to the second distance.
