Patent ID: 8119304

Claim:
An electronic board comprising: a fuel passage layer that comprises an insulating material and that defines at least one inner fuel passage space, the fuel passage layer including a plurality of openings formed into a surface of the fuel passage layer, the openings enabling a fuel to be communicated from the inner fuel passage to a power generator of a fuel cell, wherein the openings are formed at positions corresponding to fuel ports, and wiring patterns formed on both sides of the fuel passage layer such that positions of the wiring patterns are different than the positions of the openings; a first wiring layer including an insulating base and wiring patterns formed on both surfaces of the insulating base, the first wiring layer formed on the surface of the fuel passage layer and including a plurality of openings, each one of the openings of the first wiring layer fluidly connected to a respective one of the openings formed into the surface of the fuel passage layer; and a second wiring layer including an insulting base and wiring patterns formed on both surfaces of the insulating base, the second wiring layer formed on a second surface of the fuel passage layer such that the fuel passage layer is an inner layer, wherein wirings formed on both sides of the first wiring layer, the fuel passage layer and the second wiring layer are electrically interconnect through contact holes formed in the first wiring layer, the fuel passage layer and the second wiring layer.
