Zusammenfassung:	PROBLEM TO BE SOLVED: To operate an electronic device incorporating a silicon carbide semiconductor element installed on an automobile at an optimum temperature. SOLUTION: In an automobile equipped with a fuel cell 4 and a fuel tank (liquid hydrogen tank) 3 that retains fuel of -100°C or lower, the fuel is supplied from the fuel tank 3 to the fuel cell 4, and a circulation passage 9 is provided for connecting the fuel tank 3 to a coolant passage 8 provided at the periphery of the electronic device (inverter) 1 incorporating the silicon carbide semiconductor element S. The electronic device 1 is cooled by circulating the fuel as a coolant through the circulation passage 9. COPYRIGHT: (C)2005,JPO&NCIPI
