The purpose of the present is to reduce production costs for oxidative treatment of positive electrodes with regard to aluminum-based fuel cell cases. More specifically, the present invention relates to a method for producing a fuel cell case which is used for storing fuel cells and is made of aluminum or an aluminum alloy. To this end, formed in the fuel cell case is a penetration hole inserted into a pin which determines a position of the fuel cell case when loading the fuel cell case to vehicles. In addition, alumite is formed on a surface of the fuel cell case by oxidation-treating the positive electrode which uses the surface of the penetration hole as a contact point. |
