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.

Fuel cell

A fuel cell includes: an electrolyte membrane; a fuel-side catalyst layer placed on one surface of the electrolyte membrane; an oxidant-side catalyst layer placed on another surface of the electrolyte membrane; a fuel-side gas-diffusion layer placed on a main surface of the fuel-side catalyst layer; an oxidant-side gas-diffusion layer placed on a main surface of the oxidant-side catalyst layer; a pair of separators that hold the fuel-side gas-diffusion layer and the oxidant-side gas-diffusion layer therebetween; a frame that surrounds outer peripheries of the fuel-side gas-diffusion layer and the oxidant-side gas diffusion layer; a fuel-side seal member placed on a main surface of the fuel-side gas-diffusion layer; and an oxidant-side seal member placed on a main surface of the oxidant-side gas-diffusion layer. In the fuel cell, no spaces are provided between the fuel-side gas-diffusion layer and the fuel-side catalyst layer and between the oxidant-side gas-diffusion layer and the oxidant-side catalyst layer.

Polymer electrolyte fuel cells and production method thereof

Provided is a layered electronic circuit device capable of realizing high-density/high-function mounting, easily inspecting and repairing the respective constituent elements, and improving the electronic connection characteristic. The layered electronic circuit device includes a first circuit substrate () and a second circuit substrate () which are arranged in parallel such that their substrate surfaces are opposed to each other. The peripheral portion of the first circuit substrate () and the peripheral portion of the second circuit substrate () are connected to each other by connection members (to) having a wiring member () and a thermal hardening anisotropic conductive sheet (), thereby performing electric connection.
