Centrifugal air compressor anti-surge device for fuel cell engine

The invention provides a centrifugal air compressor anti-surge device for a fuel cell engine, which is characterized in that an air compressor is mounted on a first pipeline, the air outlet end of an intercooler is communicated to the first air inlet end of a humidifier through a second pipeline, and the first air outlet end of the humidifier is communicated to the air inlet end of an electric pile through a third pipeline; according to the centrifugal air compressor anti-surge device for the fuel cell engine, calculation is carried out through the air flow and the bypass flow required by the idling or small-current working condition (that is, when bypass deflation is needed in the working process of the engine, the bypass solenoid valve is installed on the bypass solenoid valve, the bypass solenoid valve is installed on the bypass solenoid valve, and the bypass solenoid valve is installed on the bypass solenoid valve when bypass deflation is needed in the working process of the engine. The bypass electromagn
