Abstract
A fuel cell case includes: a casing portion provided with a through hole that communicates between an internal space for accommodating a fuel cell stack and outside of the casing portion; a lid portion attached to an outer surface of the casing portion by a first connection portion so as to close the through hole; and a cover portion arranged on the lid portion and attached to the outer surface of the casing portion. It is configured that at least one of the lid portion and the first connection portion is fractured when an internal pressure of the casing portion is increased to be equal to or higher than a predetermined pressure and that the cover portion remains to be attached to the casing portion even after at least one of the lid portion and the first connection portion is fractured.
