Zusammenfassung: | A mathematical model is presented that allows studying multistage processes of electrooxidation and electroreduction of metal ions with account for reduction of hydrogen ions and molecular oxygen in a flow-through 3D electrode. The mathematical model takes into account the possibility of redistribution of the flow rate of electrolyte, porosity, specific surface area, specific electrode conductivity, and other characteristics in the local electrode bulk in the course of electrolysis. Model equations and results of numeric studies are presented for the electrochemical process in a flow-through 3D electrode of a carbon fiber material for the Fe(III)/Fe(II)/Fe system with account for the reaction of electroreduction of hydrogen ions and molecular oxygen. |
