Abstract: A gas diffusion layer for a fuel battery is used, which is configured by a porous member containing conductive particles, conductive fibers and a polymer resin as main components. An aggregate of the conductive fibers is formed inside the porous member, and an area ratio of the aggregate in any cross-section of the porous member is 0.5% or more and 8% or less. Further, a membrane electrode assembly including the gas diffusion layer for the fuel battery is used. Further, a fuel battery including the gas diffusion layer for the fuel battery is used.

Abstract: A fuel cell includes: an electrolyte membrane; a cathode positioned on a first surface of the electrolyte membrane; an anode positioned on a second surface of the electrolyte membrane; a cathode-side sealant positioned on a surface of the cathode different from the electrolyte membrane side of the cathode; an anode-side sealant positioned on a surface of the anode different from the electrolyte membrane side of the anode; a cathode-side separator positioned on a surface of the cathode-side sealant different from the cathode side of the cathode-side sealant; and an anode-side separator positioned on a surface of the anode-side sealant different from the anode side of the anode-side sealant. The anode-side separator has a projection on a surface stacked on the anode-side sealant, or the cathode-side separator has a projection on a surface stacked on the cathode-side sealant.

Abstract: A fuel cell module includes an electrode membrane assembly and a pair of separators. The electrode membrane assembly includes an electrode portion and a pair of gas diffusion layers. The electrode portion includes a polymer electrolyte membrane, an anode electrode formed on a first surface of the polymer electrolyte membrane, and a cathode electrode formed on a second surface of the polymer electrolyte membrane. One of the pair of gas diffusion layers is in contact with an anode surface of the electrode portion at which the anode electrode is disposed, and the other is in contact with a cathode surface of the electrode portion at which the cathode electrode is disposed. The separators sandwich the electrode membrane assembly from respective the anode surface and the cathode surface. The electrode membrane assembly and each separator are adhered to each other by a plurality of resin portions.

Abstract: A fuel-cell stack includes a cell stack having first and second flow channels, all of which extend in a direction of stack of single cells so as to open on an end surface in the direction of stack, and also includes a manifold piping structure connected to openings of the first and second flow channels. The manifold piping structure includes first and second connecting pipes respectively connected to the openings of the first and second flow channels, and a plate-like member disposed on an end surface of the cell stack to connect the first and second connecting pipes. A groove or an opening is formed in a first or second surface of the plate-like member at a location between a seal contact surface around one of the first connecting pipe and a seal contact surface around the second connecting pipe.
