Abstract
A fuel cell includes a power generation unit. A first resin frame member is provided in an outer portion of a first membrane electrode assembly of the power generation unit. The first metal separator has a heating portion subjected to spot heating from a surface of the first metal separator for allowing the first resin frame member to be melted partially. The first metal separator and the first membrane electrode assembly are welded together by a plurality of welding portions to form a first structural body.
Claims4
A fuel cell formed by stacking a membrane electrode assembly and a metal separator, the membrane electrode assembly including electrodes and an electrolyte membrane interposed between the electrodes, a resin frame member being provided in an outer portion of the membrane electrode assembly,
- wherein the metal separator has a heating portion subjected to spot heating from a surface opposite to a contact surface of the metal separator which contacts the resin frame member, for partially melting the resin frame member to weld the metal separator and the resin frame member together;
- and
- the fuel cell includes a structural body formed by combining the metal separator and the membrane electrode assembly together.
