<p><P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of operating at a high power generation efficiency stably for a long period of time, as to a fuel cell using liquid as fuel. <P>SOLUTION: The fuel cell system operates a load adjustment part 8 connected to a fuel cell stack to give the latter a load variation. A difference of output response of the fuel cell stack is found against the load variation, and from the output response value and data preliminarily stored in the control part, a fuel state of fuel supplied to a power generating part 7 is estimated. A supply volume of fuel supplied to the fuel cell stack is controlled so that the state of the fuel supplied to the power generating part 7 fall within a given range. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
