Abstract

The invention relates to a fuel cell high-dimensional model real-time simulation technology based on a tridiagonal matrix algorithm, which realizes the real-time simulation of a high-dimensional modelof a proton exchange membrane fuel cell. In the simulation technology, a tridiagonal matrix system of gas convection motion is established in a fuel cell serpentine pipe; according to the geometricalcharacteristics of the serpentine flow channel of fuel cell, a tridiagonal matrix system of fluid diffusion motion is established; the numerical algorithm of tridiagonal matrix is deduced; the mathematical model of fluid convection and diffusion and the tridiagonal matrix system are written into the real-time simulator in C language; the model is simulated in real-time and the output results areobtained. The invention simultaneously realizes high fidelity and model calculation efficiency of a fuel cell physical multi-dimensional physical model through reasonable model assumptions and advanced numerical algorithms.

Description

technical field [0001] The invention relates to the technical field of real-time simulation of a high-dimensional model of a proton exchange membrane fuel cell, in particular to a real-time simulation technology of a high-dimensional model of a fuel cell based on a tridiagonal matrix algorithm. Background technique [0002] As a hydrogen energy conversion device, a fuel cell directly converts the electrochemical energy in hydrogen into electrical energy. In practical applications, how to design peripheral auxiliary control equipment such as air compressors to optimize the performance of fuel cell systems has become the focus of research on large-scale commercial applications of fuel cells. Under such a research background, constructing an accurate and real-time high-dimensional physical model of proton exchange membrane fuel cell can describe the dynamic characteristics of fuel cell charging and discharging more accurately, and at the same time, its internal high-dimensional...
