Claim Text:
1. A membrane electrode assembly, comprising a high temperature proton exchange membrane disposed between an anode electrode and a cathode electrode; wherein a catalyst and at least one additive are disposed in a layer applied at an interface between the membrane and each of the anode and cathode electrodes wherein the at least one additive comprises an organic or inorganic acid material, acid salt fluoropolymer, perfluoroacid electrolyte, or an ionomer in an amount of between about 1% and 15% of a weight of the catalyst at the interface; wherein the at least one additive is in immediate contact with the catalyst thereby creating enhanced reaction kinetics at the interface, including enhanced oxygen reduction kinetics at the cathode interface; and wherein the resulting assembly has a power density per unit area of between about 180 and 300 mW/cm
