Abstract
An analytical basis defining the steady‐state conditions occurring in an electrolysis cell is stated. Several assumptions are made which permit a theoretical determination of the void fraction and current density distributions. The effect of void fraction and inlet velocity on cell performance is shown. Experimental data for the void fraction and slip ratio occurring in an electrolysis cell are presented. It is found that the slip ratio is near unity. This result is of importance in defining the cell void fraction distributions and is prerequisite to an analysis of pressure drop in electrolysis cells.Keywords
