<P>PROBLEM TO BE SOLVED: To provide resistance measurement equipment which can measure effective resistance of a fuel cell efficiently in a short time. <P>SOLUTION: The diagnostic equipment 1, which measures the effective resistance of the fuel cell BT, has a signal generation section 11 that generates signals for measurement including a 1st alternate current signal for measurement for measuring membrane resistance, which forms a part of the effective resistance, and a 2nd alternate current signal for measurement for measuring a reaction resistance, which forms a part of the effective resistance, and has a measurement section 12 that obtains a resistance value of the membrane resistance based on a current value of the 1st alternate current signal for measurement flowing in the membrane resistance in a state where the signal for measurement is impressed on the fuel cell BT, and voltage which is generated in the membrane, and also obtains the resistance value of the reaction resistance based on the current value of the 2nd alternate current signal for measurement flowing in the reaction resistance, and the voltage which is generated in the reaction resistance. <P>COPYRIGHT: (C)2003,JPO |
