Provided is a fuel cell capable of stopping, during abnormal heat generation, a supply of fuel and/or air, and preventing additional abnormal heat generation. In an electrode structure (a heat generation section), a fusible porous film is disposed between a cathode electrode and a cathode-side exterior member, and a fusible porous film is disposed between an anode electrode and an anode-side exterior member. The fusible porous films and may be made of resin having a low melting point and being not soluble in fuel (methanol), or may be made of a combination of a porous film and polyolefin wax with a low melting point. When abnormal heat generation occurs in the fuel cell 1, the fusible porous films and are melted by heat, and pores formed thereto disappear so that a supply of fuel and/or air can be cut off without fail.
