<P>PROBLEM TO BE SOLVED: To provide a fuel cell control system and a fuel cell control method for controlling the deterioration of a cell. <P>SOLUTION: A fuel cell control system 1 includes a fuel cell 110, an AC impedance measuring device 120, an inverter 130, and a control part 140. The AC impedance measuring device 120 measures the AC impedance of the fuel cell 110. The control part 140 discriminates peak Z"max of imaginary number component of the AC impedance to applied frequency of AC current applied during measurement, and obtains peak frequency ω<SB>o</SB>corresponding to Z"max. Next, the control part 140 obtains AC frequency ω<SB>f</SB>of AC current which the inverter 130 applies. And then the control part 140 sets ω<SB>o</SB>to the prescribed frequency different from ω<SB>f</SB>based on the obtained ω<SB>o</SB>and ω<SB>f</SB>. <P>COPYRIGHT: (C)2010,JPO&INPIT |
