A flow path member (78) includes an orifice section (80), a pressure regulating section (82), a filter section (84), and a distribution section (86) joined together integrally, and these components are detachably provided between insulating seals (76, 77). In the orifice section (80), orifice holes (80a) are formed around a fuel gas supply passage (30). In the pressure regulating section (82), a substantially ring shaped pressure regulating chamber (82a) is formed. In the filter section (84), a plurality of filter holes (84a) are formed. The orifice holes (80a) and the filter holes (84a) are connected through the pressure regulating chamber (82a). In the distribution section (86), a plurality of distribution grooves (86a) for distributing the fuel gas flowing through the fuel gas supply passage (30) in a stacking direction to flow along an separator surface, and a circular groove (86b) for supplying the fuel gas to the filter section (84) are formed. |
