Abstract
As part of the methodology to control gas permeability of functional materials, a mathematical approach is considered that takes into account a diffusion process through a plate with the boundary conditions of the 1st and 2nd order. The methodology under discussion provides methods for estimating parameters of the diffusion by using methods of singular points, functional scale and the statistical moments. A computer software packages HPRON was developed that provides mathematical modeling, planning, processing and interpretation of the results of different variants of the method of gas permeability. The results are used to optimize the performance of the membrane electrode assembly (MEA) for the automotive fuel cell and electrolyser applications with with a perfluorinated proton-conducting membrane such as Nafion.
