Nitrogen cumulative concentration calculation method, device, equipment and medium

The invention relates to a nitrogen cumulative concentration calculation method, device and equipment and a medium. The method comprises the following steps: acquiring the total flow of an electric pile anode outlet, the hydrogen concentration of the electric pile anode outlet, the electric pile anode water vapor content, the electric pile anode liquid water content and the power generation duration of a fuel cell system; obtaining the stack anode nitrogen concentration according to the stack anode outlet total flow, the stack anode outlet hydrogen concentration, the stack anode water vapor content and the stack anode liquid water content; and based on the power generation duration, obtaining the nitrogen accumulation concentration according to the stack anode nitrogen concentration integral. Therefore, the problems of influence and the like caused by gas permeation rate change due to membrane permeation characteristic change, galvanic pile performance change and the like caused by long-time operation of the
