Abstract: 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.

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.
