The invention provides a fuel cell air filter performance online detection method, a fuel cell and a vehicle. The fuel cell air filter performance online detection method comprises the following steps: comparing an obtained target rotating speed of an air compressor with an allowable maximum value, if the target rotating speed exceeds the allowable maximum value, considering that the air filter is abnormal, and dynamically adjusting the output power of a fuel cell system according to the obtained normal rotating speed of the air compressor. The air compressor is detected according to the comparison result of the target rotating speed of the air compressor and the allowable maximum value, pressure sensor hardware equipment is not used, and the outlet pressure of the air compressor is not used. Therefore, the purposes of low cost, resource saving and timely response are achieved.
本发明提供了一种燃料电池空滤性能在线检测方法、燃料电池及车辆。其中,燃料电池空滤性能在线检测方法,包括:将获取的空压机的目标转速与允许的最大值进行比较,若目标转速超过允许的最大值则认为空滤异常,并根据获取的空压机的正常转速动态调节燃料电池系统输出功率。通过空压机的目标转速与允许的最大值比较结果对空压机进行检测,不使用压力传感器硬件设备,不用空压机的出口压力。从而达到成本低、节约资源且响应及时的目的。
