An end plate is joined to a fuel cell stack. A first piping unit and a second piping unit are attached to the end plate. The first piping unit has a first attachment base, to which a fuel gas supply pipe, a first oxidation off-gas discharge pipe, and a coolant discharge pipe are coupled. The second piping unit has a second attachment base, to which an oxidation gas supply pipe, a coolant supply pipe, and a discharge pipe are coupled. The discharge pipe is joined to a discharge cylinder coupled to the first oxidation off-gas discharge pipe. The oxidation gas supply pipe and the coolant supply pipe are integrated with each other. Also, the first oxidation off-gas discharge pipe and the coolant discharge pipe are integrated with each other. |
