Title: Fuel cell system for vehicle
Inventor: AKAHORI KOICHI
IPC: H01M8/04
Filed: 2003-03-14
Abstract: <P>PROBLEM TO BE SOLVED: To prevent applying sharp temperature change caused by cooling water in starting of a system to a fuel cell.  <P>SOLUTION: Before cooling water is supplied to the fuel cell 1, a control part 5 detects the temperature of the cooling water in a cooler 2 and a bypass passage 3c with temperature sensors 9b, 9c. The control part 5 controls a mixing ratio of cooling water from the cooler 2 and the cooling water from the bypass passage 3c according to detected temperature with a three-way valve 8 to control the temperature of the cooling water supplying to the fuel cell 1 in an appropriate range. Thereby, for example, since the supply of the extremely high temperature or low temperature cooling water to the fuel cell 1 can be prevented, applying sharp temperature change caused by the cooling water in starting of the system to the fuel cell 1 can be prevented.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
