Researchers from Delft University of Technology (TU Delft, The Netherlands), in collaboration with colleagues from the École Polytechnique Fédéral de Lausanne (EPFL, Switzerland), have found a simple yet very effective solution to greatly increase the efficiency and stability of hydrogen production through solar-driven water splitting. By separating the positive and the negative electrodes using a bipolar membrane, they were able to create local optimal conditions for electrolysis. Furthermore, they achieved this using only Earth-abundant catalysts and solar cells, opening the way for more efficient and stable water-splitting systems at lower cost. They have published their findings in the latest Advanced Energy Materials.
