Stack humidification method, device and electronic equipment

Abstract

The invention provides a stack humidification method, device and electronic equipment, comprising: controlling the operation of the target stack, and calculating the required humidification water volume of the cathode and the anode of the target stack based on the operating parameters during the operation of the target stack; Determine the membrane reverse osmosis volume of the proton exchange membrane in the target stack; calculate the cathode intake humidity and anode intake humidity of the target stack respectively according to the amount of water to be humidified at the cathode, the amount of water to be humidified at the anode, and the volume of membrane reverse osmosis; based on the cathode intake Humidity and anode inlet humidity to humidify the target stack. The present invention can more reasonably humidify the stack.

Description

technical field [0001] The present invention relates to the technical field of electric stacks, and in particular, to a method, device and electronic equipment for humidifying electric stacks. Background technique [0002] During the operation of the fuel cell, the water content in the stack directly affects the performance of the stack. When the humidification water content in the stack is low, the proton exchange membrane is in a dry state, and the proton conductivity decreases, but when the humidification water content is high When the battery is flooded, the battery will be flooded, so the appropriate humidification water content helps the stack to work in the best humidity state, which can increase the service life of the stack to a certain extent. In the stack humidification method provided by the related art, when humidifying the stack in the operating state, it follows the principle that the larger the discharge current is, the more water is produced by the reaction,...
