Electrochemical Systems

Our research focuses on investigating multi-scale transport phenomena in electrochemical processes and bridging the gap between fundamental research and large-scale industrial applications. Our work spans topics such as water electrolysis, electrodeposition, and hydrogen fuel cells. A key emphasis is placed on green hydrogen production through water electrolysis and the underlying processes within various types of electrolyzers.

Design of new-concept electrolyzer

Alkaline Water Electrolysis (AWE) is the most mature technology for producing the green hydrogen needed to transition to a net-zero emission industry. Howe­ver, AWE still lacks efficiency and operation at high current densities. Therefore, new electrolyzer designs need to be investigated to o­vercome these issues.

Electrode performance and degradation test

Nickel electrodes are widely used in alkaline water electrolysis, but the electrode o­verpotentials remain high, resulting in significant losses. Improving bubble ­manage­ment on industrially relevant electrodes is therefore beneficial, as bubbles lead to increased ohmic resistance and block the active electrode area.
