Abstract
The present disclosure provides a performance prediction method and system for a fuel cell in an anode recirculation mode. The method includes: calculating output results of a membrane water transfer equation, a liquid water transfer equation, and a temperature transfer equation based on the membrane water transfer equation, the liquid water transfer equation, and the temperature transfer equation inside the fuel cell; calculating output results of a gas transfer equation based on output results of a first labeling equation according to a phenomenon of nitrogen transmembrane permeation inside the fuel cell; determining gas state parameters in the anode recirculation mode based on the output results of the temperature transfer equation and the gas transfer equation; and predicting output voltage performance of the fuel cell based on the gas state parameters in the anode recirculation mode and output results of a second labeling equation.
