20090214917 | FUEL CELL, FUEL CELL STACK, AND METHOD FOR MANUFACTURING FUEL CELL - A fuel cell includes a membrane electrode assembly (MEA) having an electrolyte membrane and a pair of electrodes arranged on both sides of the electrolyte membrane in the thickness direction, a pair of frames having a frame shape and holding an outer periphery portion of the electrolyte membrane, a pair of gas diffusion layers arranged inside the pair of frames and on both sides of the MEA in the thickness direction, and a gasket covering at least a part of the pair of frames. The fuel cell further includes a first cross-linking adhesive member formed of rubber which includes a membrane accommodating portion having an indented shape for accommodating the outer periphery portion of the electrolyte membrane and a first intermediate portion interposed between the pair of frames and which is subjected to cross-linking adhesion with the outer periphery portion of the electrolyte membrane and the pair of frames. | 08-27-2009 |
20100040933 | FUEL CELL SEPARATOR, METHOD FOR MANUFACTURING THE FUEL CELL SEPARATOR, AND FUEL CELL - A fuel cell separator is provided with an opening that functions as a manifold. A resin coating is formed within the peripheral area of the fuel cell separator, in a state where the power generation area is masked with a masking jig. Subsequently, the masking jig is removed, and a conductive coating is formed within the power generation area of the fuel cell separator, the peripheral area of which has been masked by the resin coating. | 02-18-2010 |
20100055530 | POLYMER ELECTROLYTE FUEL CELL - Each of collectors | 03-04-2010 |
20100227246 | PLATE MEMBER FOR FUEL CELL, MANUFACTURING METHOD OF THE PLATE MEMBER, AND FUEL CELL - There is disclosed a plate member for a fuel cell which is laminated together with a membrane-electrode assembly to constitute a fuel cell having cells and is provided with a channel forming portion which forms a fluid channel to supply and discharge a fluid to/from the membrane-electrode assembly and/or the cells. The plate member for the fuel cell includes a first covering portion which covers the channel forming portion, and a second covering portion which covers an edge of the first covering portion together with a portion around the edge of the first covering portion. | 09-09-2010 |

20090042085 | PROCESS FOR PRODUCING SEPARATOR AND SEPARATOR - In fuel cell separator, the periphery of manifold through which fuel gas, reaction water, etc., pass and the seal line being a site of bonding with an adjacent separator are provided with a resin layer. Within the surface of the separator, the resin application site on which the resin layer is formed undergoes subbing treatment in advance to thereby increase the capability of bonding with the resin. When the resin layer consists of a resin having an NH group, as the subbing treatment, hydroxide deposition treatment is carried out on the surface of the separator. | 02-12-2009 |
20090324812 | FUEL CELL SEPARATOR AND METHOD FOR MANUFACTURING SAME - A fuel cell separator is provided with an opening that functions as a manifold. A resin coating is formed within the peripheral area of the fuel cell separator, in a state where the power generation area is masked with a masking jig. The resin coating is formed so that the separator substrate is exposed within at least a portion of the peripheral area. Subsequently, the masking jig is removed, and a conductive coating is formed within the power generation area of the fuel cell separator, the peripheral area of which has been masked by the resin coating. The conductive coating is formed by causing electricity to flow through the portion of the peripheral area where the separator substrate is exposed. | 12-31-2009 |
