A fuel cell (100) that generates power without discharging fuel gas includes: an electrolyte membrane (810); an anode (820) provided on one side of the electrolyte membrane; and a fuel-gas passage portion (840) provided on the outer side of the anode to form a fuel-gas supply passage through which fuel gas is supplied to the anode. The gas permeability of at least one of the electrolyte membrane and the anode in a thickness direction thereof varies from position to position in a direction the fuel-gas supply passage extends.
