New study reveals mechanism behind water ionization under electrochemical conditions.

Hydrogen is an important energy source for the future. Therefore, understanding the electrolysis process is essential. Researchers at the Max Planck Institute for Polymer Research and the Yusuf Hamied Department of Chemistry at the University of Cambridge have now investigated a related process, the autodissociation process, in more detail. While the fundamental chemistry of water dissociation is well understood under standard conditions, much less is known about how it behaves under the strong electric fields present in electrochemical devices.

In nature, the behavior of systems—whether large or small—is always governed by a few fundamental principles. For instance, objects fall downward because it minimizes their energy. At the same time, order and disorder are key variables that also shape physical processes. Systems—especially our homes—tend to become increasingly disordered over time. Even at the microscopic level, systems tend to favor increased disorder, a phenomenon known as an increase in the so called “entropy”.
