Abstract
A fuel cell system includes a fuel cell, a control valve and a controller. The fuel cell is configured to receive anode gas and cathode gas to generate electric power. The control valve is configured to control pressure of the anode gas being fed to the fuel cell through an anode flow channel. The controller controls the control valve to periodically increase and decrease the pressure of the anode gas flowing through the anode flow channel in an area downstream of the control valve. The controller sets an anode pressure differential value for the anode gas resulting from periodic increasing and decreasing of the pressure of the anode gas based on a requested fuel cell output. The controller determines a quantity of liquid in the anode flow channel. The controller decreases the anode pressure differential value that was set based on the requested fuel cell output.
