A Differential Alkaline Electrolysis Cell to Study Scaling Effects
What conclusions about the behavior of large electrolysis stacks can be drawn from small lab cell experiments? The concept of a differential electrolysis cell was developed in this work to answer this question. The cell allows for the setting of local operating conditions corresponding to specific positions inside an electrolyzer. This paves the way to
