<P>PROBLEM TO BE SOLVED: To provide a control device of a fuel cell system which can detect the drying state of an electrolyte membrane surely and in an early stage. <P>SOLUTION: The control device (25) of the fuel cell system is provided with a measuring means for measuring a pressure loss of a fuel gas in the fuel cell, a calculating means which, based on the pressure loss of the fuel gas measured by the measuring means, calculates a lowered amount of the pressure loss of the fuel gas in a predetermined time duration, and a diagnosing means which, based on the lowered amount of the pressure loss of the fuel gas calculated by the calculating means, diagnoses the drying state in the fuel cell by determining that there exist such cells in which a portion of an electrolyte membrane becomes dry and partial deviation occurs in a reaction region of an electrolyte membrane. <P>COPYRIGHT: (C)2009,JPO&INPIT |
