PROBLEM TO BE SOLVED: To provide a fuel cell system capable of preventing occurrence of problems due to clogging of a filter by detecting the clogging of the filter easily.SOLUTION: In step 100, liquid level h1 on the outside of a filter is detected by an outside water level sensor. In step 110, liquid level h2 on the inside of the filter is detected by an inside water level sensor. In step 120, the difference &Dgr;h between the liquid level h2 on the inside of the filter and the liquid level h1 on the outside of the filter is determined. In step 130, a determination is made as to whether or not the difference &Dgr;h between the liquid level h2 on the inside of the filter and the liquid level h1 on the outside of the filter goes above a threshold &Dgr;hTH. In step 140, an alarm indicating that the degree of clogging is high, and that it is the time of replacing (or cleaning) the filter is issued. |
