摘要:
A fuel cell in which gas short-cutting is prevented without reducing effective area for electrode reaction. At least one of a fuel gas flow path and an oxidizing gas flow path includes flow grooves having bends and fluid flowing between ends of the flow grooves. The effective reaction area of the flow grooves on a separator plate is rectangular, having a first side in the direction along which the bends are aligned longer than a second side in the direction along their main extents, located upstream and downstream of the bends, where the fluid flows in opposing directions.

A fuel cell that prevents gas slippage, with minimal reduction in effective area for electrode reaction. At least one of a fuel gas flow path and an oxidizing gas flow path is configured with flow channels having bends and so that gas flows between ends of the flow channels, and, among ridges between a neighboring upstream-side portion of a flow channel and a downstream-side portion of the flow channel, a gas diffusion layer touching at least a ridge between an upstream region of the flow channel on the upstream side and a downstream region of the flow channel on the downstream side, has a lower porosity than the gas diffusion layer touching other ridges and touching the flow channels.

A solid polymer fuel cell includes a membrane junction unit being provided an electrolyte membrane sandwiched by an oxidant electrode and a fuel electrode and two separators being sandwiched from both surfaces of the electrolyte membrane, the two separators being provided, in central portions of surfaces of the two separators, with gas flow channels, respectively, and a sealing portions being provided between surfaces of the two separators which are opposed to each other and between surfaces of the two separators which are opposed to the outer peripheral edge portion, respectively, in which the sealed surfaces of the two separators, which are opposed to the sealing portions, respectively, are provided with a plurality of depressions, which are independent of one another in a direction of the sealed surfaces, so that the plurality of depressions surround the gas flow channels.
摘要:
A fuel cell in which the sealed portions formed at the peripheral edges of gas flow passages of a gas separating plate are turned so that they have a U-shaped cross section in the direction of the lamination so as to provide for elasticity. A filling member is filled in the interior of the sealed portions. This gas separating plate is used to respectively form gas flow passages through which different gas fluids are caused to flow so that they are electrochemically reacted in a pair of electrode reacting portions disposed with an electrolyte layer being interposed therebetween. In consequence, the sealed portions provided at the peripheral edges of the gas flow passages deform in accordance with the creep caused in the electrode reacting portions. This enables a balanced, adequate bearing pressure to be kept applied to the electrode reacting portions and the sealed portions, thereby enabling the fuel cell to be operated in an excellent gas sealed state for a long time.
摘要:
An internal reforming type fuel cell comprising, as reforming regions packed with a reforming catalyst, a first reforming region which is thermally held in contact with a unit fuel cell and which does not adjoin a fuel gas side electrode and a second reforming region which adjoins the fuel gas side electrode. Part of a fuel gas externally supplied is reformed in the first reforming region, whereupon the partly reformed fuel gas is supplied into the second reforming region.

An electric storage device pressure regulating apparatus includes: a case in an internal portion of which is disposed a regulating chamber that communicates with a space in a vessel by an opening portion; a semipermeable membrane that seals the opening portion; a check valve that stops discharging of the gas out of the vessel from inside the regulating chamber when the internal pressure of the regulating chamber is less than or equal to a predetermined value, and that discharges the gas out of the vessel from inside the regulating chamber when the internal pressure of the regulating chamber exceeds the value; and a communicating pipe that communicates between a space inside the regulating chamber and a space inside the vessel and extends from the case to an electric storage device main body.
摘要:
A internal reforming type molten carbonate fuel cell is provided in which the process or flow direction of the reforming reaction of a raw fuel gas in the reforming reaction section is countercurrent to the flow direction of the oxidant gas in the cell reaction section. Therefore, a temperature difference in the fuel cell can be suppressed.
摘要:
A reforming catalyst adapted for use with fuel cells is disclosed which is free from degradation in catalytic activity even if subjected to a fuel gas containing an electrolyte or substances resulting therefrom, and which has stable and high catalytic activity for an extended period of time. The reforming catalyst includes a catalytically active substance adapted to reform a fuel gas containing hydrocarbons or alcohols into a fuel gas containing hydrogen and carbon monoxide, and an electrolyte-removing substance adapted to remove an electrolyte and/or substances resulting therefrom in the fuel cell. The electrolyte-removing substance has a porous structure and comprises a compound containing at least one of silicon, aluminum and chromium which chemically reacts with the electrolyte and/or the substances resulting therefrom for removal thereof.
