<P>PROBLEM TO BE SOLVED: To provide a cooling system for a fuel cell vehicle motor which can provide a cooling condition required for each motor while simplifying cooling channels by using pure water generated in the fuel cell as a coolant. <P>SOLUTION: The cooling system of this fuel cell vehicle motor is provided with a piping channel of returning pure water exhausted from the fuel cell to the fuel cell 50, in the fuel cell vehicle comprising the fuel cell 50 which generates electric power using hydrogen and oxygen and exhausts pure water generated in power generation, and at least two motors 2, 3 including a drive motor, and a plurality of motors are arranged along the flowing direction of the pure water in series in this piping channel, and rotors 2a, 3a, and stators 2b, 3b installed in the motors are cooled by supplying the pure water into respective motors. By this system, the motors installed in the fuel cell vehicle can be cooled by the pure water exhausted from the fuel cell, and the piping channels flowing the coolant for cooling the motors can be simplified. Thereby, freedom of piping layout is improved and cost reduction and weight reduction of the piping can be realized. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
