ABSTRACT:
A fuel cell includes an electrolyte electrode assembly and a pair of separators sandwiching the electrolyte electrode assembly. 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 the anode of the electrolyte electrode assembly, and the second protrusions contact the cathode of the electrolyte electrode assembly. A channel member is provided on a surface of the separator facing the cathode. The channel member forms a plurality of fuel gas supply channels connected between a fuel gas supply passage and a fuel gas inlet for supplying a fuel gas into a fuel gas flow field.
