<P>PROBLEM TO BE SOLVED: To provide a fuel cell system surely suppressing the discharge of fluorine ions and metal ions. <P>SOLUTION: The fuel cell system includes a fuel cell 12 generating electric power with anode gas containing hydrogen supplied to an anode and cathode gas containing oxygen supplied to a cathode; ion removing membranes 28, 42 reducing the amount of ions contained in moisture discharged from the fuel cell 12; ion detecting means (an ion detector 54 and a flow rate detector 58) detecting the amount of ions contained in moisture discharged from the fuel cell 12 or ion concentration in the moisture discharged from the fuel cell 12; and a flow rate control valve 60 for controlling the discharged water amount from the fuel cell on the basis of the amount of ions or the ion concentration. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
