This invention proposes a diagnostic method for hydrogen exhaust valves used in fuel cells, specifically for diagnosing faults in the fuel cell power system's power generation process where the hydrogen exhaust valve cannot be opened. During power generation, it was observed that when the hydrogen exhaust valve fails to open, the pressure at the fuel cell hydrogen inlet deviates very little from the actual set pressure, remaining essentially consistent with the set pressure. It was also found that after the hydrogen exhaust valve fails to open, and the fuel cell power generation system continues to operate, impurities such as water and nitrogen accumulate at the anode, leading to performance degradation. Based on this phenomenon, this invention uses a comprehensive diagnostic approach, considering the deviation between the set hydrogen pressure and the target pressure, as well as whether the fuel cell power system experiences a voltage undervoltage fault, to comprehensively diagnose the hydrogen exhaust valve's inability to open. This method is independent of changes in fuel cell performance, is simple, convenient, and provides a more accurate diagnosis of whether the hydrogen exhaust valve is unable to open.
