<P>PROBLEM TO BE SOLVED: To provide a fuel cell system in which output of a fuel cell is controlled in consideration of an operating temperature of the fuel cell and its water balance. <P>SOLUTION: In the fuel cell system in which electricity is generated by an electrochemical reaction between a fuel cell gas (hydrogen gas) and an oxidizing gas (air), this system is provided with a memory means 501 of memorizing a temperature versus water balance output characteristic to express the water balance output of the fuel cell in which the water balance of the fuel cell against the operating temperature of the fuel cell is balanced, a temperature sensor 61 to detect the operating temperature of the fuel cell, an output setting means 502 of setting the water balance output of the fuel cell corresponding to the operating temperature detected from the temperature versus water balance output characteristic, and an output control means 503 of controlling power generation so that output of the fuel cell will not exceed the water balance output when a demand output from a load exceeds the water balance output. By that, occurrence of flooding can be suppressed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
