20100291472 | POWER GENERATING CELL FOR FUEL CELL - An electrolyte membrane on the inside of annular frames with an anode-side electrode catalyst layer, a first gas diffusion layer and a first gas flow channel-forming body stacked on top of the membrane. An electrode catalyst layer, a second gas diffusion layer and a second gas flow channel-forming body are stacked on the underside. Frames have a supply channel supplying fuel gas to the gas flow channel in the first gas flow channel-forming body, a discharge channel discharges the fuel gas. An overhang part that extends outward is on the outer peripheral edge of the first channel-forming body to overlap a flange part of the frame beyond the outer peripheral edge of the anode-side electrode catalyst layer. Penetration of seeping water can be prevented by retaining the seeping water in the overhang part. | 11-18-2010 |

20090075140 | ELECTRODE STRUCTURE OF FUEL CELL - An MEA includes an electrolyte membrane permeable to hydroxide ions. A catalyst layer formed of a hydrogen storage alloy is provided on one surface of the membrane facing the anode electrode layer. Another catalyst layer formed of platinum-on carbon is provided on the opposite surface of the membrane facing the cathode electrode layer. The catalyst layer on the anode-electrode-layer side dissociates hydrogen gas into atomic hydrogen, diffuses the atomic hydrogen by way of solid phase diffusion, and absorbs/desorbs atomic hydrogen. The catalyst layer on the cathode-electrode-layer side forms hydroxide ions from air, humidifying water, and electrons. The membrane allows movement of the hydroxide ions to the catalyst layer on the anode-electrode-layer side. This leads to formation of water on the anode-electrode-layer side, whereby occurrence of dry-up can be prevented. Even when flooding arises from formed water, atomic hydrogen can smoothly move through solid-phase diffusion. An open circuit voltage of the catalyst layer on the cathode-electrode-layer side can be made smaller than an elution potential of platinum. Since the catalyst layer on the anode-electrode-layer side absorbs excess hydrogen gas, wasteful discharge of hydrogen gas can be avoided. | 03-19-2009 |

20140017582 | FUEL BATTERY - A fuel battery includes an oxidant gas flow passage having a downstream section, in which a gas diffusion porous body is arranged. The fuel battery includes a fuel gas flow passage having a downstream section, in which a gas diffusion porous body is arranged. A cooling medium flow passage is formed between a first separator of each unit cell of the fuel battery and a second separator of a unit cell adjacent to the unit cell. The flowing direction of a cooling medium in the cooling medium flow passage is the same as that of oxidant gas in the oxidant gas flow passage. An upstream section of the cooling medium flow passage is located closer to a surface of a membrane-electrode assembly that faces the oxidant gas flow passage adjacent to the cooling medium flow passage as compared with a downstream section of the cooling medium flow passage. | 01-16-2014 |

20140162175 | FUEL CELL AND MANUFACTURING METHOD OF EXPANDED METAL - A cathode-side gas flow path of a cell that forms part of a fuel cell is formed by a first expanded metal arranged on a gas inlet side, and a second expanded metal arranged on a downstream side. The first expanded metal is such that mesh is arranged in a straight line, and gas that flows on a gas diffusion layer side is separated from gas that flows on a separator side. The gas flowrate on the gas inlet side is reduced, so the amount of produced water that is carried away is reduced. As a result, the gas inlet side is inhibited from becoming dry at high temperatures. | 06-12-2014 |
