车载燃料电池诊断装置的研究

A special diagnosis device of fuel cell vehicle

介绍了一种特殊的车载燃料电池诊断装置,该装置包括控制单元、燃料气体供给单元、电力调整单元、冷却单元和电力消耗单元。该装置可以精确地再现车辆行驶期间燃料电池堆的异常情况,便于在修理车间对其进行彻查,及时发现并排除故障。当燃料电池的冷却系统或燃料气体供给系统受到损坏时,利用该诊断装置的冷却单元和燃料气体供给单元也可以对燃料电池堆进行准确的诊断。

The paper presented a special vehicle fuel cell diagnosis device which including control unit, fuel gas supply unit, power conditioning unit, cooling unit, and electric power consumer unit. This device can accurately reappear the abnormal situation of the fuel cell when the vehicle is running, it is helpful for taking a thoroughly vehicle checking in the repair workshop, and for finding out and for removing the faults. The cooling unit and the fuel gas supply unit of this diagnosis device also can exactly diagnose the fuel cell in the case of the cooling unit and the fuel gas supply unit of the fuel cell is damaged.
