Cooling Arrangement for a fuel-cell vehicle
First Claim
1. A fuel-cell vehicle for traveling by electric power generated by supplying a reactive gas and a fuel gas to a fuel cell that is cooled by a liquid cooling system,the fuel-cell vehicle comprising:
- a first radiator and a second radiator for dissipating heat and cooling a coolant warmed by said fuel cell;
at least first and second cooling fans for ventilating cooling fins of said first and second radiators, respectively; and
an electric pump, disposed along a pipe line of said cooling system for circulating the coolant;
wherein said electric pump is disposed at a position where said electric pump can catch the flow of air created by the second cooling fan,wherein the flow of air created by the second cooling fan and directed to the electric pump is thereafter directed to the fuel cell for cooling the fuel cell.

Abstract
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.
