| 20120021318 | FUEL CELL, METHOD FOR OPERATING FULL CELL AND FUEL CELL SYSTEM - A fuel cell, a method for operating a fuel cell and a fuel cell system, which ensure no dew condensation for a wet reaction gas in the inlet area of gas channels in plates in a fuel cell stack, are provided. Gas channels | 01-26-2012 |
| 20120077103 | FUEL CELL, METHOD FOR OPERATING FULL CELL AND FUEL CELL SYSTEM - In a fuel cell stack, gas channels and heat medium channels are disposed on one surface and the other surface of one plate, respectively. Gas channels are disposed on the other plate such that they face the gas channels in the one plate. A gas inlet header is disposed at the upper part of the gas channel in the plate and a heat medium inlet header is disposed at the upper part of the heat medium channels such that they face the gas inlet header on the other side. Cooling water as a heat medium is supplied from a heat medium supply manifold hole to a heat medium inlet header. Water vapor in the reaction gas (wet fuel gas) is prevented from being condensed in the inlet area of the gas channels by heating the gas inlet header by heat conduction. | 03-29-2012 |
| 20120082908 | FUEL CELL, METHOD FOR OPERATING FUEL CELL AND FUEL CELL SYSTEM - A fuel cell, a method for operating a fuel cell and a fuel cell system, which ensure no dew condensation for a wet reaction gas in the inlet area of gas channels in plates in a fuel cell stack. Gas channels and heat medium channels are disposed on one surface and the other surface of one plate, respectively. Gas channels are disposed on the other plate such that they face the gas channels in the plate. A gas inlet header is disposed at the upper part of the gas channel in the plate and a heat medium inlet header is disposed at the upper part of the heat medium channels such that they face the gas inlet header on the other side. Cooling water such as heat medium is supplied from the heat medium supply manifold hole to the heat medium inlet header, thereby warming up the same. | 04-05-2012 |
| 20120088166 | FUEL CELL, METHOD FOR OPERATING FUEL CELL AND FUEL CELL SYSTEM - A fuel cell system comprising a fuel cell having plural membrane-electrode assemblies and plates, fuel and oxidant humidifiers and heater exchanger. Heat exchange between a supply inlet and discharge outlet is carried out between first and second heat exchange mediums. Fuel gas and oxidant gas are directed to flow parallel to each other in the fuel cell. A circulation path is established through the fuel and oxidant humidifiers and the heat exchanger by interconnection among discharge outlet, heat exchanger, fuel and oxidant humidifiers, and inlet. | 04-12-2012 |
