Alkaline Electrolyzer

Application ID: 99281

Alkaline water electrolysis is a well-established industrial process for producing hydrogen gas. In the cell, hydrogen gas is formed at the cathode whereas oxygen gas is formed at the anode.

The electrolyte is an aqueous liquid, and when the evolved gases form bubbles, the effective ionic conductivity is lowered. The generated gases may have a detrimental effect on cell performance also due to a lowered accessible surface area for the electrode reactions.

This example investigates the impact of the gas formation on the performance of an alkaline electrolysis cell.

This model example illustrates applications of this type that would nominally be built using the following products:
