Patent ID: 8080345

Claim:
A high capacity micro fuel cell system for supplying power to an electronic device, comprising: a fuel supply comprising a fuel inlet formed at one side of a substrate and a gas outlet formed at an other side of the substrate, the substrate having a channel formed therein; a pair of cell units disposed at opposed sides of the substrate of the fuel supply, each of the cell units comprising an anode catalyst layer, a cathode catalyst layer, and an electrolyte layer between the anode and cathode catalyst layers to generate current with fuel supplied through the fuel supply; outer substrates disposed at outer sides of the cell units, each of the substrates having through holes formed therein to define a plurality of oxygen supplies for supplying oxygen to corresponding cathode catalyst layers of the cell units; and a holder integrally assembling the substrate of the fuel supply, the pair of cell units and the outer substrates of the oxygen supply, wherein the holder comprises a mixture of polydimethylsiloxane and silica materials.
