摘要： A fuel cell system includes a target pressure setting unit configured to periodically and repeatedly set a target upper limit pressure and a target lower limit pressure as a target pressure of anode gas. An upper limit pressure setting unit is configured to set the smaller one of an upper limit value based on durability performance and an upper limit value based on output performance as an upper limit pressure of the anode gas. The target pressure setting unit sets a value smaller than the upper limit value as the target upper limit pressure when the upper limit value based on the durability performance of the fuel cell is selected as the upper limit pressure of the anode gas, and sets a pressure higher than the upper limit value as the target upper limit pressure when the upper limit value based on the output performance is selected.

摘要： For implementing a stop control which extracts a current from a fuel cell and consumes a cathode side oxygen at a system stop, the current extraction from the fuel cell is ended in a state that a certain quantity of oxygen smaller than when the current extraction is started remains on a cathode side of the fuel cell. With this, the hydrogen movement to the cathode side after the system stop can be effectively suppressed and thereby a cathode internal hydrogen concentration at the system start can be kept low, thus making it possible to properly process the cathode side hydrogen at the system start.

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 method for controlling the anode pressure of a fuel cell is disclosed, with hydrogen fed to the anode via a feed-pressure control unit, and a gas/condensate mixture periodically discharged from the anode via a discharge-pressure control unit into a reservoir, with the gas portion fed back to the anode. To effect feedback of hydrogen the pressure in the reservoir is adapted to that in the hydrogen feed means during discharge, whereupon the discharge-pressure control unit is closed and the feed-pressure control unit and a feedback-pressure control unit are controlled such that the pressure in the reservoir changes due to consumption at the anode until a desired pressure in the reservoir is reached and/or a preset pressure in the anode is reached, whereupon the feedback-pressure control unit and the feed-pressure control unit are controlled such that the pressure in the anode adapts to a preset desired value.
