Abstract
A proton exchange membrane fuel cell that includes: a positive electrode; a negative electrode; a polyelectrolyte membrane; and platelet-shaped nanoparticles of gold, platinum, palladium, silver, copper or their alloys or mixtures thereof. The polyelectrolyte membrane includes a sulfonated tetrafluoroethylene based fluoropolymer-copolymer and is disposed between the positive electrode and the negative electrode. The nanoparticles contact the surface of the proton exchange membrane increase the efficiency of the fuel cell by at least 50%.
