“Natural Water to Hydrogen" will establish a new research profile at the UDE, in which the research fields of "water research" and "hydrogen" will be synergistically combined. Specifically, the project aims to increase the sustainability of hydrogen production through anion exchange membrane (AEM) water electrolysis. For the first time, a fundamental understanding is to be gained of how water quality, electrodes and membranes influence each other. Organic and inorganic lead substances will be used to quantify how/to what extent water needs to be purified before and during electrolysis. The new research profile will combine the UDE strategic research areas water research and nanosciences (catalysis) in the field of "Natural Water to Hydrogen".
