Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a fuel cell in which only a surface alignment technique is necessary for assembling a vapor access hole. SOLUTION: This method includes a stage of etching a surface of a substrate (12) and forming channels (24, 26) and a stage of forming pedestals (54, 88) on the surface of the substrate. Anode sides (56, 89) demarcating fuel regions (68, 102) positioned to the channels (24, 26) are included in the pedestals. Electrolytes (46, 96) are arranged between anode sides (56, 89) and cathode sides (58, 90), and the fuel regions (68, 102) are capped by insulators (66, 98). One part of the substrate (12) is removed from the rear face, and the channels (24, 26) are exposed. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: A method is provided for fabricating a hybrid gas diffusion layer/current collector/electrocatalyst structure (28) suitable for 3D microfuel cell devices (180). The method comprises forming a macroporous electrically conductive structure (28) on a substrate (12, 112) positioned such that a plurality of cathode current collector/GDL (168) and anode current collector/GDL (166) are formed. An electrocatalyst material (158) is deposited in contact with these structures, completing the formation of cathode (168) and anode (166) hybrid current collector/GDL/electrocatalyst structures. When electrolyte (158) is positioned between the electrocatalyst material (158) contacting the cathode collector (168) and the electrocatalyst material (158) contacting each of the plurality of anode collectors (166), the resulting MEA is suitable for use in a micro fuel cell device.

Abstract: A method is provided for fabricating a fuel cell that requires only front side alignment techniques to fabricate gas access holes. The method comprises etching the front side of a substrate ( 12 ) to provide a channel ( 24, 26 ), and forming a pedestal ( 54, 88 ) on the front side of the substrate, wherein the pedestal ( 54, 88 ) comprises an anode side ( 56, 89 ) defining a fuel region ( 68, 102 ) aligned with the channel ( 24, 26 ). An electrolyte ( 46, 96 ) is positioned between the anode side ( 56, 89 ) and a cathode side ( 58, 90 ), and the fuel region ( 68, 102 ) is capped with an insulator ( 66, 98 ). A portion of the substrate ( 12 ) is removed from a back side to expose the channel ( 24, 26 ).
