Interface Engineering for Water Electrolysis

Water electrolysis is seen as one of the most promising ways to overcome the inherently fluctuating nature of renewable energy sources by storing surplus energy in the form of chemical energy, i.e., hydrogen gas.

Different electrolyzer systems come with their pros and cons. A special focus has to be set on understanding interfaces of the system components and their changes under operation and during aging; from transient catalyst dissolution to surface corrosion and passivation of cell components.
