Patent abstract
A fuel cell includes electrolyte electrode assemblies and a pair of separators sandwiching the electrolyte electrode assemblies. Each of the separators has a first small diameter end portion to form a fuel gas supply passage therein, and circular disks sandwiching the electrolyte electrode assemblies to form a fuel gas flow field and an oxygen-containing gas flow field. The first small diameter end portion is integral with circular disks each having a relatively large diameter through a plurality of first bridges. The first bridges extend radially outwardly from the first small diameter end portion at equal angles.
