A method for diagnosing degradation of a fuel cell stack, including: S, qualitatively determining a degradation type of the fuel cell stack according to a voltage-current curve of the fuel cell stack; S, 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; S, 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.

Method for diagnosing degradation of fuel cell stack, method for multi-point analysis of fuel cell, and method for estimating performance of fuel cell membrane electrode

A multi-environment integrative thermal management method for a fuel cell vehicle is provided. The method can ensure the accuracy and the stability of the control for a temperature of a fuel cell system of the fuel cell vehicle in a complicated and changeable environment, decrease the energy consumption of the entire vehicle, and increase the economical efficiency of the entire vehicle.
