Abstract
A fuel cell is formed by stacking membrane electrode assemblies and metal separators. The metal separator is formed by adhering and joining together an anode separator and a cathode separator. In the metal separator, a step is provided on an outer circumferential end of the cathode separator, the step being spaced from an outer circumferential end of the anode separator. An adhesive layer is formed on the step between the outer circumferential end of the cathode separator and the outer circumferential end of the anode separator.
