To inhibit an electric pump from generating heat with a simple structure when the electric pump is used in a cooling system. A two-wheeled fuel-cell vehicle is provided with a cooling system to cool a fuel cell. A first radiator and a second radiator are provided to cool the cooling water warmed by the fuel cell with a flow of air. A cooling fan functions so as to ventilate the cooling fins of the first radiator and the cooling fans function so as to ventilate the cooling fins of the second radiator. An electric pump is disposed in the middle of a pipe line for the circulation of the cooling water. The electric pump is disposed at a position where the electric pump can catch the flow of air created by the cooling fan.
