PROBLEM TO BE SOLVED: To provide a fuel battery which uniformly flows a cooling medium in a separator even if a passage of a cooling medium is formed in a second direction and a passage of an oxidation gas is formed in a first direction, and to provide a separator.SOLUTION: Multiple first inner walls, multiple second inner walls, and multiple third inner walls are formed in a separator. The multiple first inner walls extend in a first direction between a first hole formed at one end of the separator and a second hole formed at the other end when viewed in a first direction. The multiple second inner walls are formed between the first hole and the multiple first inner walls. The multiple third inner walls are formed between the second hole and the multiple first inner walls. The multiple second inner walls and the multiple third inner walls include multiple grooves and multiple recessed parts facing the multiple grooves. Each of the multiple grooves extends along the first direction between the hole and the multiple first inner walls in the separator. Each of the multiple recessed parts is recessed from the inner side to the outer side of the separator and extends along the second direction between one of the multiple grooves and another groove in the separator. |
