The invention relates to a method for increasing the cold start capability and the load application capability and power capacity of airplanes while simultaneously oxygen-depleting the system exhaustgas, wherein supply air (7) is compressed in a compressor (3) of an inerting system (1) and is guided into a gas separator (4) of the inerting system (1), from which an oxygen-enriched gas (8) and a nitrogen-enriched gas (9) are discharged. Additionally, a cathode exhaust gas (10) is discharged from a fuel cell (2) and is liquefied by means of a condenser (5), wherein water is separated from the liquefied cathode exhaust gas (10) using a water separator (6). The invention is characterized in that the oxygen-enriched gas (8) is guided into the fuel cell (2) by a cathode inlet of a fuel cell (2). 本发明涉及一种通过消耗系统废气中的氧气来提高飞机的冷启动能力以及负载施加能力和功率容量的方法，其中，在惰化系统(1)的压缩机(3)中压缩供应空气(7)并将其输送到惰化系统(1)的气体分离器(4)中，从该气体分离器中排出富氧气体(8)和富氮气体(9)，其中，还从燃料电池(2)中排出阴极废气(10)并通过冷凝器(5)液化，其中，通过水分离器(6)将水从液化的阴极废气(10)中分离，其特征在于，将富氧气体(8)通过燃料电池(2)的阴极入口输送到燃料
