Channel member for providing fuel gas to separators forming a plurality of fuel gas fields on one surface

Abstract

A fuel cell includes electrolyte electrode assemblies and a pair of separators sandwiching the electrolyte electrode assemblies. Each of the separators is a single plate, and includes a plurality of circular disks. First protrusions and second protrusions are provided on both surfaces of the circular disk. The first protrusions contact an anode of the electrolyte electrode assembly, and the second protrusions contact a cathode of the electrolyte electrode assembly. A channel member is provided on a surface of the separator facing the cathode. The channel member has a second bridge. When a load in a stacking direction is applied to the second bridge of the channel member, the second bridge is deformable in the stacking direction.
