Disclosed are a fuel cell power net system and a method for controlling the same. The fuel cell power net system includes: a fuel cell controller configured to control current output from a fuel cell unit; at least one DC/DC converter configured to boost DC voltage and to output the boosted DC voltage; a battery connected to the fuel cell unit in parallel so as to supply DC power to the fuel cell unit; a load controller configured to provide demand output information; and a fuel cell power controller configured to receive the demand output information, to calculate output levels required by the fuel cell unit and the battery, to compare a current output level of the fuel cell unit with the output level required by the fuel cell unit, and to provide a control value to the fuel cell controller depending on a result of the comparison.

Power net system for fuel cells and method for controlling the same

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.
