The invention provides a membrane nitrogen production and fuel cell coupled fuel tank inerting system, which is used for inerting a fuel tank by taking low-oxygen-content air generated by the system as inert gas besides providing electric energy for an airplane after the system is loaded on the airplane, so that the fuel tank is in a non-combustible state, the generated heat can be used for heating air and water or preheating fuel, the generated water can be used for domestic water or coolant and the like after being treated, and when inert gas generated by the fuel cell is insufficient to inert the fuel tank, the membrane inerting system is started to ensure that the fuel tank is always in a non-combustible state. According to the invention, the airborne power generation efficiency can beeffectively improved, the product of the fuel cell is fully utilized, the resource utilization rate is high, the engine air entraining amount of the membrane inerting system is reduced, the compensation loss is reduced, and the membrane nitrogen production and fuel cell coupled fuel tank inerting system is suitable for occasions with insufficient air entraining or low air entraining pressure.

    本发明提供了一种膜制氮与燃料电池耦合的燃油箱惰化系统,在飞机上装载后,除了为飞机提供电能外,利用其产生的低含氧量的空气作为惰性气体来惰化燃油箱,使其处于不可燃的状态,产生的热量可于加热空气、水或燃油预热,产生的水处理后可用于生活用水或冷却剂等用途,当燃料电池产生的惰性气体不足以惰化燃油箱时,开启膜惰化系统,保证油箱始终处于不可燃状态。本发明可以有效地提高了机载发电效率,并充分利用了燃料电池的产物,资源利用率高,同时减少了膜惰化系统的发动机引气量,降低了代偿损失,适用于引气不足或引气压力低的场合。
