Abstract:
1. A monolithic fuel cell, comprising: a) a plurality of triplex anode layer-electrolyte layer-cathode layer sandwiches, said triplex sandwiches further comprising a plurality of anode layers, a plurality of cathode layers, and a plurality of electrolyte layers; and b) a plurality of substrate interconnect gas diffusion flow field layer constructs, further comprising a plurality of fuel passages and a plurality of oxidizer passages, said substrate interconnect gas diffusion flow field layer constructs comprising a substrate means for providing electrical interconnection between adjacent anode and cathode layers, providing gas diffusion, and providing a flow field for reaction by-products, said substrate interconnect gas diffusion flow field layer constructs being interposed between said anodes and cathodes and containing said fuel and oxidizer passages, wherein said anode layers and said cathode layers are made from a mixture comprising a porous conductive polymer doped with nano-scale catalyst and carbon particles.
