Abstract

A generalized theoretical analysis of the kinetics of the hydrogen oxidation reaction under the Volmer- Heyrovsky-Tafel mechanism on an electrode covered by polymeric films is presented. The treatment includes the diffusion of the molecular hydrogen through the electrolyte solution, as well as through the different layers and interfaces. On the light of the resulting expressions, the applicability of the Levich-Koutecky diagrams for the determination of the kinetic current densities was critically analyzed.

膜电极上氢氧化反应的动力学研究。第一部分:理论方面
对聚合物薄膜电极上的氢氧化反应动力学在Volmer- Heyrovsky-Tafel机制下的广义理论分析。处理包括氢分子通过电解质溶液以及通过不同层和界面的扩散。根据所得表达式,批判性地分析了leich - koutecky图在确定动力学电流密度方面的适用性。
