Abstract
A fuel cell system includes a fuel cell, a controller, a resistance sensor, and a regulator. The fuel cell has a cathode plate, an anode plate, and an ion-exchange membrane interposed between the cathode plate and the anode plate. The controller is for controlling a gas flow rate to the anode plate. The resistance sensor is coupled to the fuel cell for measuring a resistance of the fuel cell. The regulator is coupled to the controller and coupled to the anode plate for regulating the gas flow to the anode plate. The controller receives a signal from the resistance sensor and is configured to control the regulator to adjust the gas flow to the anode plate based on the signal from the resistance sensor.
