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.
