摘要： A hydrogen supply method for a fuel cell system, for supplying hydrogen according to a state of the fuel cell system when the fuel cell system is started, includes steps of (a) measuring a stop time period which elapses until the fuel cell system is started after the fuel cell system is stopped, (b) determining whether a reaction time period consumed to complete a reaction of residual hydrogen and residual oxygen residing in a fuel cell stack since the fuel system is stopped is not more than the stop time period, and (c) when it is determined in the step (b) that the stop time period is less than the reaction time period, closing a purge valve that is able to discharge gases accommodated in an anode from the anode and supplying at the same time hydrogen to the anode such that an internal pressure of the anode becomes a predetermined first target pressure.

摘要： A method for controlling startup of a fuel cell vehicle is provided. The method includes starting to adjust supply of hydrogen and air to a fuel cell and setting a control voltage of a side of a main bus end of a converter disposed between the main bus end and a high-voltage battery to a predetermined lowest control voltage. An output voltage of the side of the main bus end of the fuel cell and the control voltage of the side of the main bus end of the converter are then compared to adjust an amount of air supply to the fuel cell based on the comparison.

摘要： A method and a system for controlling startup of a fuel cell are provided. The method includes sensing a startup request signal and boosting a Bi-directional high-voltage DC/DC Converter (BHDC) of a main bus stage when the startup request signal has been sensed by a controller. A valve of an air/hydrogen line is then opened together with the boosting of the BHDC and the startup of the fuel cell is completed by allowing an output of the fuel cell after the valve of the air/hydrogen line is opened.
