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.

摘要： A fuel cell system includes a fuel cell, a control valve and a controller. The controller controls the control valve to periodically increase and decrease the anode gas pressure downstream of the control valve. The controller executes a shutdown/restart operation of the fuel cell by closing the control valve to stop the anode gas and shutting down power generation of the fuel cell upon receiving a shutdown command, and restarting feeding of the anode gas and restarting the power generation upon a prescribed operation restart condition being met. The controller estimates an anode gas concentration at a location where the anode gas concentration is locally lower within a power generation region of the fuel cell based on a control state of the anode gas when the shutdown command is issued. The controller sets the prescribed operation restart condition for executing the shutdown/restart operation based on the anode gas concentration.

The controller estimates an anode gas concentration at a location where the anode gas concentration is locally lower within a power generation region of the fuel cell based on a control state of the anode gas at a time the shutdown command is issued. The controller determines whether to permit or prohibit shutting down the power generating operation based on the anode gas concentration.
