Abstract

In this paper, we implement the most rigorous approach to the mathematical description of two-phase transfer processes in liquid water, water vapor, and non-condensable gases (hydrogen and oxygen) in gas-diffusion electrodes/current collectors of water electrolyzers based on a polymer electrolyte membrane. The solution to this problem allowed the following to be determined: various movement modes of gas–liquid flows and their effects on electrolyzer performance; optimal parameters of gas-diffusion electrodes (thickness, porosity, permeability, wetting angle), depending on the required operating mode of the electrolyzer (current density, temperature, pressure); and possible reasons for the incorrect operation of the electrolyzer.

气体扩散电极中两相传质对高分子电解质膜电解槽特性的影响研究

摘要

在本文中，我们采用最严格的方法对基于水的水扩散器/集热器中的液态水，水蒸气和不可冷凝气体（氢和氧）中的液态水，水蒸气和非冷凝性气体（氢和氧）的两相转移过程进行数学描述。聚合物电解质膜。该问题的解决方案可以确定以下内容：气液流动的各种运动方式及其对电解器性能的影响；气体扩散电极的最佳参数（厚度，孔隙率，渗透率，润湿角），取决于电解槽所需的工作模式（电流密度，温度，压力）；以及电解槽操作不正确的可能原因。
