Abstract
An apparatus includes a stack voltage monitor that measures a voltage of each channel of a plurality of channels of a fuel cell stack. Each of the channel of the plurality of channels includes a predetermined number of unit cells. The stack voltage monitor calculates impedance of each of the channel from the measured voltage. The apparatus further includes a controller that diagnoses a state of the fuel cell stack based on the impedance of each of the channel.
