Abstract:
1. A membrane electrode assembly for a fuel cell comprising: an electrolyte membrane; an anode catalyst layer and a cathode catalyst layer, each being formed on a respective side of the electrolyte membrane; an anode current collector formed on the anode catalyst layer and a cathode current collector formed on the cathode catalyst layer, wherein the anode current collector and the cathode current collector each independently comprise at least one transition metal selected from the group consisting of Au, Ag, Al, Ni, Cu, Pt, Ti, Mn, Zn, Fe, Sn, alloys thereof and an electrically conductive polymer; and an anode diffusion layer formed on the anode current collector and a cathode diffusion layer formed on the cathode current collector, wherein the anode diffusion layer and the cathode diffusion layer are electrically nonconductive.
