摘要： A fuel cell stack obtained by stacking a plurality of fuel cells has an internal manifold that extends in a stacking direction of the fuel cells to externally discharge a gas used in the fuel cell, and an extension member that adjoins an inner wall surface of the internal manifold and extends in the stacking direction. The extension member is a bar-shaped member provided in an opposite side to a side where a gas from the fuel cells flows to the inside of the internal manifold and has a sloping surface making an acute angle with an inner-wall lower surface of the internal manifold.

摘要： 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.
