Abstract:
An electrode structure adapted for use with a fuel cell system, characterized in that the electrode structure comprises a silicon substrate having one or more selectively doped regions thereon, wherein each of the one or more selectively doped regions is adapted to function as a currant collector for the transmission of an electrical current, and wherein the silicon substrate further comprises one or more discrete porous bulk matrix regions disposed across a top surface, wherein each of the one or more discrete bulk matrix porous regions is defined by a plurality of pores that extend into the silicon substrate, wherein the plurality of pores defines line pore surfaces, wherein the inner pore suites have catalyst particles uniformly dispersed thereon, and wherein the one or more selectively doped regions corresponds to the one or more discrete porous bulk matrix regions, and wherein the plurality of pores are interconnecting mesoporous acicular pores, interconnecting macroporous acicular pores, or a combination thereof.
