主权项 1. A product fuel cell comprising: a solid polyelectrolyte membrane having a first face and an opposite second face; a first layer comprising a catalyst overlying the first face of the membrane; a first microporous layer overlying the first layer comprising a catalyst, and wherein the first microporous layer includes a plurality of microchannels formed therein open toward a first layer comprising a catalyst; a first gas diffusion media layer overlying the first microporous layer; and wherein each of the microchannels of the first microporous layer are defined by a surface that is free of cracks, wherein each of the microchannels in the first microporous layer has a depth ranging from about 10-20 μm; and, wherein at least a portion of the microchannels are directed in a direction towards an inlet of a reactant gas supply comprising said fuel cell.
