氢燃料电池发动机多种限功率工况的应用试验

Application Test of Hydrogen Fuel Cell Engine under Various Power Limiting Conditions

氢燃料电池发动机主要由空气子系统、氢气子系统、冷却子系统等组成。各子系统均有各自不同的性能指标,当各自的性能指标均满足当前工况的要求时,燃料电池发动机才可以正常运行。当某个指标达不到当前要求但车辆仍然需要运行时,就需要进入限功率工况,保证车辆的基本功能正常运行。文章主要基于空气子系统、氢气子系统、冷却子系统等不同性能指标进行相应的限功率工况的应用测试。

Hydrogen fuel cell engine is mainly composed of air subsystem,hydrogen subsystem and cooling subsystem.Each subsystem has its own different performance indicators,when the respective performance indicators meet the requirements of the current working condition,the fuel cell engine can run normally.When a certain indicator does not meet the current requirements but the vehicle still needs to run,it is necessary to enter the limited power condition to ensure the normal operation of the basic functions of the vehicle.Based on the different performance indexes of air subsystem,hydrogen subsystem and cooling subsystem,the paper conducts the corresponding application test of the limited power condition.
