<P>PROBLEM TO BE SOLVED: To provide a fuel cell system suppressing the consumption of hydrogen, fuel for forming hydrogen, or the like, quickly conducting warming of a fuel cell, and immediately starting power generation in the fuel cell after warming, in a simple system constitution, and also to provide the warming method of the fuel cell system. <P>SOLUTION: The fuel cell system 1 has the fuel cell 2 equipped with an anode passage 22, a cathode passage 23, and an electrolyte body 21, and a cathode pump 3 connected to an inlet part of the cathode passage 23. Discharge pressure of the cathode pump 3 in the starting of the fuel cell before power generation of the fuel cell 2 is increased to the pressure higher than stationary discharge pressure which is discharge pressure in power generation of the fuel cell 2 to raise temperature of discharge gas of the cathode pump 3. By supplying the temperature-raised discharge gas as the cathode gas Gc to the cathode passage 23, warming of the fuel cell 2 is quickly conducted. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
