✦ Synopsis

A mathematical model was developed to describe the performance of hydrogen electrode catalyst particles that are bonded to the proton exchange membrane of a hydrogen-bromine fuel cell. Macrohomogeneous porous electrode theory was applied to the catalyst particles. Fundamental equations were used to describe the transport of protons and dissolved hydrogen in the catalyst zone. The distribution of the electrode particles in this zone was also included in the model. Parametric studies on the numerical solution to this model indicate that the performance of the membrane electrode assembly is optimized when the volume fraction of polymer and catalyst is equal in the catalyst zone.
