Abstract
During two-phase electrolysis for hydrogen or fluorine industrial production,
there are bubbles that are created at vertical electrodes, which imply quite
important electrical properties and electrochemical processes disturbance.
Bubbles are motion sources for the electrolysis cell flow, and then hydrodynamic
properties are strongly coupled with species transport and electrical
performances. The presence of the bubbles modifies these global and local
properties: the electrolysis cell and the primary to ternary current density
distribution are modified. This disturbance leads to the modification of the local
current density.
The goal of this proposition is to present the electrochemical engineering
study and modelling of two-phase electrolysis properties at electrode vicinity.
This work is due to the necessity for a better knowledge of the actual interface
condition during electrolysis, for example to have a better process optimisation
or electrode consumption prevention.
Keywords: two-phase electrolysis, modelling, electrochemical engineering.
