Abstract
The present invention provides improved, low-cost fuel cells having reduced fuel crossover, reduced sensitivity to metal ion impurities and ability to operate under a broad range of temperatures. Additionally, new effective organic fuels are described for use in such fuel cells. The invention further provides improved methods for catalyst preparation and a new integrated flow field system for use in H.sub.2 /O.sub.2 fuel cells. The fuel cell includes a proton conducting membrane having pore diameters which are essentially smaller than 30 nanometers.
