<P>PROBLEM TO BE SOLVED: To provide a control device of a fuel cell system capable of reducing the load on the fuel cell and improving the durability thereof by instructing and controlling to input a constant DC current during power generation, because it is possible to control a DC current value in a manner of slightly lending toward suppression when the fuel cell starts to deteriorate. <P>SOLUTION: A control device of a fuel cell system comprises a hydrogen generator 1; a fuel cell 4 for generating power by making the generated gas obtained by the generator 1 react with an oxidant gas; a controller 7 for controlling a series of operations from the start to the power generation; and a DC-AC convertor 5 for converting DC power generated from the fuel cell 4 into AC power. The durability of the controller 7 can be improved by instructing and controlling the convertor 5 so as to input the constant DC current during the power generation to reduce the load on the fuel cell 4 as much as possible. That is, fuel cell protective control, capable of controlling the DC current in accordance with the power generating capability of the fuel cell 4, becomes possible. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
