Abstract

A one-dimensional porous electrode (PE) model and additional consideration of the dependence of the local solution conductivity on its gas saturation was used to study the effect of simultaneous hydrogen evolution on distribution of the potential in PE and the overall rate of the target redox reaction. It was found that this effect depends on the ratio of conductivities of the solid κs and liquid κl phases and direction of solution supply and can be both negative (rear supply at any κs and κl, front supply at κs ≫ κl), and positive (front supply at κs ≤ κl). However, variation of the target reaction rate in all cases for PE with a high specific surface area is low (10–40%). It is shown that in the terms of the model of a homogeneous gas-liquid mixture, a weak effect of gaseous hydrogen is related to the specific form of profiles κl(x) far from the earlier considered ideal (or inverse) liquid-phase conductivity profiles.
