20100136460 | FUEL CELL - An object of the present invention is to provide a fuel cell including a reaction gas supply path which makes it difficult to cause water condensation in a region near an end plate. | 06-03-2010 |
20110027681 | PRESERVATION ASSEMBLY OF POLYMER ELECTROLYTE FUEL CELL STACK - A preservation assembly of a polymer electrolyte fuel cell stack is provided. The assembly includes an uninstalled polymer electrolyte fuel cell stack and sealing units. The uninstalled polymer electrolyte fuel cell stack is provided with an oxidizing agent passage having an inlet and an outlet and extending through a cathode and a reducing agent passage having an inlet and an outlet and extending through an anode. The sealing units include sealing plugs or containers and are configured to seal the inlet and the outlet of the oxidizing agent passage within which an oxygen concentration has been decreased and to seal the inlet and the outlet of the reducing agent passage within which the oxygen concentration has been decreased. The uninstalled polymer electrolyte fuel cell stack is in a state before an assembled polymer electrolyte fuel cell stack is incorporated into a fuel cell system. | 02-03-2011 |

20120189931 | FUEL CELL POWER GENERATION SYSTEM AND OPERATION STOP METHOD OF THE SAME - A fuel cell power generation system including a fuel cell, a fuel generator, an oxidizing gas supply device, an output controller, an open-close mechanism, and a controller. The controller is configured such that in a stop process, the controller controls the output controller to stop supplying the electric power to an external load; controls the oxidizing gas supply device to stop supplying an oxidizing gas and controls the open-close mechanism to close a passage upstream from an oxidizing gas channel; after the passage upstream from the oxidizing gas channel is closed, stops a raw material gas supply device and a water supply device when a predetermined period has elapsed, during which period a gas in the oxidizing gas channel is replaced by a fuel gas. | 07-26-2012 |
20120214080 | METHOD OF PRESERVING POLYMER ELECTROLYTE FUEL CELL STACK AND PRESERVATION ASSEMBLY OF POLYMER ELECTROLYTE FUEL CELL STACK - A preservation assembly of a PEFC stack which is capable of sufficiently inhibiting degradation of performance of the PEFC stack particularly during a time period that elapses from when the stack is placed in the uninstalled state until it is placed in the installation position and is practically used. The PEFC stack is provided with an oxidizing agent passage having an inlet and an outlet and extending through a cathode and a reducing agent passage having an inlet and an outlet and extending through an anode. The PEFC stack is preserved in an uninstalled state in such a manner that an interior of the oxidizing agent passage and an interior of the reducing agent passage are set in a pressure-reduced state. | 08-23-2012 |
