Abstract:
A fuel cell includes an electrolyte electrode assembly and separators. The separator includes first through third plates which are stacked together. A fuel gas channel connected to a fuel gas supply passage is formed between the first and third plates. The fuel gas channel forms a fuel gas pressure chamber between the first and third circular disks. Further, an oxygen-containing gas channel connected to an oxygen-containing gas supply passage is formed between the second and third plates. The oxygen-containing gas channel forms an oxygen-containing gas pressure chamber between the second and third circular disks.
