20090087714 | Tubular Fuel Cell Module - A fuel cell module that includes: a plurality of tubular fuel cells, each of which contains a cylindrically shaped inner electrode that exhibits conductivity, a first catalyst layer, an electrolyte layer, and a second catalyst layer laminated sequentially to the outer peripheral surface of the inner electrode, and an external coil that exhibits conductivity and is wound around the outer peripheral surface of the second catalyst layer in such a manner that a first coil section with a loose winding pitch is sandwiched between second coil sections with a tight winding pitch; and a current collecting member that exhibits conductivity and is provided with a plurality of openings into which the tubular fuel cells can be inserted, wherein the first coil sections and the openings fit together. | 04-02-2009 |
20090155659 | Tubular Fuel Cell - A tubular fuel cell includes an inner current collector, a membrane-electrode assembly, and seal portions provided at the axial end portions of the membrane-electrode assembly, respectively. The membrane-electrode assembly includes an inner catalyst layer provided on the inner current collector, an electrolyte membrane provided on the inner catalyst layer, and an outer catalyst layer provided on the electrolyte membrane. The axial length of the outer catalyst layer is shorter than the axial lengths of the electrolyte membrane and the outer catalyst layer. The axial end face of the outer catalyst layer and the axial end face of the inner catalyst layer are located on the opposite sides of the seal portion in each side of the tubular fuel cell. | 06-18-2009 |
20100015475 | SOLID POLYMER FUEL CELL AND METHOD FOR ACTIVATING SAME - A solid polymer fuel cell has a catalyst layer including a nanohorn aggregate as a catalyst carrier, catalyst metal supported on the catalyst carrier, and a polymer electrolyte coating the catalyst carrier. Voltage higher than the open circuit voltage of the solid polymer fuel cell is applied to the catalyst layer so as to increase triphasic interfaces at which the reaction gas reduced at the catalyst layer, the catalyst metal, and the polymer electrolyte meet. | 01-21-2010 |
20100021789 | Tubular Fuel Cell and Fuel Cell Module - A tubular fuel cell comprises a cylindrical internal electrode having electrical conductivity, a lamination of a first catalytic layer, an electrolytic layer, and a second catalytic layer laminated in that order on an outer circumferential surface of the internal electrode, and an electrically conductive exterior coil wound around an outer circumferential surface of the second catalytic layer. The tubular fuel cell further comprises an electrically conductive spacer which has an outside diameter greater than that of the exterior coil. | 01-28-2010 |
20100233568 | GAS DIFFUSION ELECTRODE, METHOD FOR MANUFACTURING THE SAME AND MEMBRANE ELECTRODE ASSEMBLY - A porous gas diffusion electrode provided on a polymer electrolyte such that a gas can be introduced, for a polymer electrolyte fuel cell, includes a carbon fiber, and an electric conductive polymer and a thermoset resin that bond the carbon fibers to each other. | 09-16-2010 |
20100233586 | TUBE-TYPE FUEL CELL - It is an assignment to provide a fuel cell whose battery performance is high, whose gas sealing performance of fuel gas and oxidizing-agent gas can be improved by means of an opposite-end construction of a single cell | 09-16-2010 |
20100239939 | TUBE-TYPE FUEL CELL - To provide a tube-type fuel cell, which has an electricity-collecting structure that makes it possible to collect electricity in axially-orthogonal directions in an outside electricity collector of single cell constituting the tube-type fuel cell, and whose electricity-collecting distance is so less as to make it possible to be of low resistance. | 09-23-2010 |
