摘要： A solenoid valve is provided to control a gas supply pressure such as a hydrogen supply valve of a fuel cell system. In particular, the solenoid valve includes: a valve body including a nozzle and a valve chamber, a nozzle opening/closing sheet, and a gas bypass hole formed on the valve body to communicate with a valve chamber of the valve body when the nozzle is closed and supply gas to a first chamber of the valve chamber through the gas bypass hole. With this arrangement, the solenoid valve may inhibit gas leak that can occur in the nozzle due to a diameter error of the nozzle due to a production deviation and a production deviation of a regulator.

摘要： A system and method for emergency starting of a fuel cell vehicle is provided. In particular, a high-voltage converter, a balance of power (BOP), and a controller are included in the system. The high-voltage converter is configured such that one side thereof is connected to a high-voltage battery via a battery switch and the other side thereof is connected in parallel to a plurality of fuel cells. The BOP is connected in parallel to the high-voltage converter and the fuel cells. The controller is configured to control the power supplied from the high-voltage battery to the BOP without conversion by connecting the battery switch upon the failure of the high-voltage converter or high-voltage battery.

摘要： An oxygen supply apparatus and method for a fuel cell of an aircraft are provided. The oxygen supply apparatus includes a compressor that generates compressed air by compressing air in the atmosphere and supplies the compressed air to a fuel cell stack, an oxygen tank having a predetermined amount of oxygen stored therein. An aircraft monitoring device monitors the aircraft and determines whether oxygen supply from the oxygen tank is required, and an oxygen supply means switching device switches an oxygen supply means for the fuel cell stack from the compressor to the oxygen tank, or vice versa depending on an outcome of the monitoring.

摘要： A system and method for controlling a fuel cell of a vehicle are provided. The method includes sensing a time point when pressure control is necessary by sensing whether an output of the fuel cell is additionally necessary or whether the fuel cell can be in a dry-out state. In response to sensing that the pressure control is necessary, a required valve opening degree of an air outlet is derived by substituting a target air pressure for a data map. A fuel cell air outlet valve is then adjusted based the derived valve opening degree of the air outlet.
