FUEL CELL AND FUEL CELL SEPARATOR HAVING A COOLING MEDIUM REGULATING PORTION

摘要

In a fuel cell having a separator 14a in which main cooling water channels 32 are formed, a separator 14b for another unit cell 2 stacked on the cooling water channel formation surface side of the separator 14a, and a second sealing member 101 c interposed between the separators 14a and 14b to seal a cooling medium flowing in the main cooling water channels 32, an outer peripheral rib 15 for regulating the flow of cooling water to the second sealing member 101 c side is provided inside relative to the second sealing member 101 c in the separator surface direction in order to improve the efficiency of cooling with the cooling medium.
