<P>PROBLEM TO BE SOLVED: To solve the problem that much time and energy are required between triggering of a fuel cell and completion of warming up. <P>SOLUTION: A part or the entire cathode discharge gas from a fuel cell stack 2 which is housed in a case 1 can be introduced into the case by a switching valve 19. By introducing the cathode discharge gas whose temperature is raised at triggering into the case, the temperature of the atmosphere of the fuel cell stack in the case rises, and the warming up time in a low temperature condition is shortened while energy is saved. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
