<P>PROBLEM TO BE SOLVED: To improve heat radiation efficiency in a fuel cell stack and make the temperature distribution of the whole fuel cell stack more uniform. <P>SOLUTION: A heat radiation space SP is formed along the lamination direction of a unit cell and a separator of a fuel cell unit and an injection nozzle 55 for cooling water supply is arranged in the heat radiation space SP. Air is supplied from the heat radiation space SP to an oxygen chamber, water is injected, and thereby, the fuel cell stack 100 is cooled from the inside. <P>COPYRIGHT: (C)2007,JPO&INPIT |
