Abstract
Provided are a method and an apparatus controlling a water flooding failure in a fuel cell dual-stack system. The method includes: acquiring a hydrogen pressure drop reference value of the stack system in each normal working condition to obtain a control value; collecting a current pressure drop at a hydrogen side, and determining whether the current pressure drop at the hydrogen side is higher than the control value corresponding to a current normal working condition; determining a faulted stack according to voltages or currents of the first stack and the second stack if the current pressure drop at the hydrogen side is higher than the control value corresponding to the current normal working condition; reducing an opening degree of a flow regulating valve of the faulted stack, and increasing an opening degree of a flow regulating valve of the other stack.
