<P>PROBLEM TO BE SOLVED: To improve determination accuracy of a catalyst poisoning state in a fuel cell system. <P>SOLUTION: A method of determining a catalyst poisoning state of the fuel cell system includes a step of acquiring a predicted value of a low-load voltage of the fuel cell system, a step of actually measuring the low-load voltage after the voltage of the fuel cell system is lowered to a value smaller than a preset threshold voltage value, and a step of determining the catalyst poisoning state of the fuel cell system based on a comparison result of the predicted value and actually-measured value of the low-load voltage. <P>COPYRIGHT: (C)2011,JPO&INPIT |
