摘要： A fuel cell electrode structure includes a membrane electrode assembly including an electrolyte membrane between a pair or electrodes, and a frame being integrally formed with the membrane electrode assembly supporting the membrane electrode assembly from the peripheral side.The membrane electrode assembly includes a gas diffusion layer on the surface, and a sealing member for sealing the periphery of the membrane electrode assembly is provided on the frame.The sealing member includes a lip portion, and at least partly includes extended portion that extends to the membrane electrode assembly. The extended portion is thinner than the lip portion of the sealing member, and the end face of the extended portion is in contact with the end face of the gas diffusion layer.

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 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. 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.

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.
