The invention provides an oxygen supply apparatus and method for a fuel cell of an aircraft. The oxygen supply apparatus includes a compressor that generates compressed air by compressing air in the atmosphere and supplies the compressed air to the fuel cell stack, and an oxygen tank in which a predetermined amount of oxygen is stored. The aircraft monitoring device monitors the aircraft and determines whether oxygen needs to be supplied from the oxygen tank, and the oxygen supply mode switching device switches the oxygen supply mode of the fuel cell stack from the compressor to the oxygen tank according to the result of the monitoring, or vice versa. 本发明提供用于飞行器的燃料电池的氧气供应设备和方法。氧气供应设备包括压缩机和氧气罐，所述压缩机通过压缩大气中的空气来产生压缩的空气，并且将压缩的空气供应至燃料电池堆，所述氧气罐中储存有预定量的氧气。飞行器监测装置监测飞行器并且确定是否需要从氧气罐供应氧气，并且氧气供应方式切换装置根据监测的结果将燃料电池堆的氧气供应方式从压缩机切换到氧气罐，或者相反。
