    摘要： A system for activating a fuel cell includes a flow meter for measuring the amount of water discharged from an outlet of the air electrode and an outlet of the fuel electrode; a pressure sensor for measuring the pressure at the respective outlets; and a back pressure regulator receiving flow values measured by the flow meters and pressure values measured by the pressure sensors, which are fed back from a controller, and regulating a pressure difference (ΔP=PCathode−PAnode) to be a value greater than 0. With the system, the activation time of a fuel cell and the amount of hydrogen used for the activation can be reduced, thus improving the productivity and manufacturing cost.

    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.
