Abstract

See full text

A method for diagnosing degradation of a fuel cell stack, including: S10, qualitatively determining a degradation type of the fuel cell stack according to a voltage-current curve of the fuel cell stack; S20, quantitatively measuring parameter values of each of individual cells of the fuel cell stack according to the degradation type, and quantitatively determining a degradation degree of each of the individual cells according to the parameter values; S30, determining a uniformity degradation degree among the individual cells of the fuel cell stack according to a non-uniformity degree of a voltage distribution of the individual cells. By qualitatively determining the degradation type of the fuel cell stack, the degradation condition of the entire fuel cell stack may be obtained.
