Fuel cell and fuel cell stack

摘要

A fuel cell (10) includes an electrolyte electrode assembly (26) and separators (28). The separator (28) has a fuel gas supply passage (36), a fuel gas distribution passage (76a), an oxygen-containing gas supply passage (50), and an oxygen-containing gas distribution passage (84a). The fuel gas flows through the fuel gas supply passage (36) into the separator (28). The fuel gas distribution passage (76a) connects the fuel gas channel (76) and the fuel gas supply passage (36). The oxygen-containing gas flows through the oxygen-containing gas supply passage (50) into the separator (28). The oxygen-containing gas distribution passage (84a) connects the oxygen-containing gas channel (84) and the oxygen-containing gas supply passage (50).
