Abstract:
An electrode assembly adapted for use with a fuel cell, comprising:an anode derived from a first planar silicon substrate; an electrolyte; a cathode derived from a second planar silicon substrate; wherein the anode and the cathode are spaced apart and substantially parallel to each other so as to define a spaced apart region, and wherein the electrolyte is interposed between the anode and the cathode, and wherein the anode and the cathode each have a plurality of porous regions that define anode pore surfaces and cathode pore surfaces, and wherein the anode pore surfaces and the cathode pore surfaces each have a catalyst dispersed thereon such that the catalyst is noncontiguously dispersed throughout the plurality of porous regions of the anode and the cathode.
