Zusammenfassung:PROBLEM TO BE SOLVED: To improve drainage of residual water in a fuel gas passage in a fuel cell.SOLUTION: An anode separator 30a includes: a hydrogen passage 34; an anode off-gas discharge section 37; an outlet buffer section 35 into which anode off-gas discharged from a terminal end of the hydrogen passage 34 flows and which has a plurality of projections 35p formed therein; and an anode off-gas lead-out passage 36 that leads the anode off-gas flowing into the outlet buffer section 35 out onto the anode off-gas discharge section 37. The outlet buffer section 35 has a hydrophilic inner wall surface. In contrast, the anode off-gas lead-out passage 36 has a water-repellent inner wall surface.
