Abstract

The invention relates to the technical field of fuel cells, in particular to a fuel cell current density distribution estimation method and device and a computer storage medium. According to the fuelcell current density distribution estimation method provided by the invention, under the condition that other sensors or sensing gaskets are not arranged, the current densities of different regions are calculated through a multi-point sampling result, so that the current density distribution of the fuel cell monomer is obtained. According to the fuel cell current density distribution estimation method, the design improvement point of an existing fuel cell is small, the improvement cost is low, and the current density distribution map of the fuel cell can be accurately obtained.

Description

technical field [0001] The present application relates to the field of fuel cell technology, in particular to a method, device and computer storage medium for estimating the current density distribution of a fuel cell. Background technique [0002] A fuel cell is an electrochemical power generation device. Its principle is that fuel (such as hydrogen) and oxidant (such as air) undergo an electrochemical reaction through a membrane electrode to generate an electromotive force. Proton exchange membrane fuel cells usually use a solid polymer membrane capable of transferring protons as the electrolyte. During the reaction, protons are transferred from the anode to the cathode through the membrane, and electrons are transferred from the anode to the cathode through an external load. At present, the fuel cell uses distributed parameter measurement data to verify the reliability of the model simulation results, and at the same time, it can characterize the state of different positi...
