Novel and industrial-grade surfaces for hydrogen electrolysis While platinum and iridium are the gold standard for hydrogen catalysis, there are numerous efforts to replace the expensive and rare raw materials with cheaper materials. In addition, the electrolysers available on the market today also require very clean water in order to be able to operate in a stable manner with a high degree of efficiency in the long term, otherwise the impurities in the field of electrolysis will continue to materialise. -         Electrolysis should be as efficient as possible – for this purpose, the electrodes are structured with the help of laser-based methods to increase the reactive surface area and at the same time accelerate the detachment of the resulting gas bubbles, which would otherwise negatively affect the overall process. -         The electrodes are said to be robust in long-term operation and against possible corrosion. For this purpose, special material systems of several combined metals are deposited directly as an alloy from a laser plasma in order to have a catalytic effect and protect the electrodes against chemical attacks from the liquid. In our cooperation, we combine the entire chain from basic research to industrial application: ·        TU Dresden, Chair of Laser-Based Manufacturing: Prof. Dr. Andres Fabian Lasagni, Dr. Robert Baumann, Mayla Barrientos, Francisco Udo Marins Almeida ·        Chair of Powder Metallurgy: Prof. Dr. Thomas Weißgärber, Matthias Gramlich, Maria Rosner ·        HZDR & TU Dresden: Chair of Transport Processes at Interfaces: Prof. Dr. Kerstin Eckert, Dr. Xuegeng Yang, Dr. Alexander Babich ·        TU Dresden, Chair of Hydrogen and Nuclear Energy Technology: Prof. Dr. Wolfgang Lippmann, Dr. Marko Swoboda, Max Hübner -------------------------------------------- This project ELECSO; SAB-100757494 is co-funded by the European Union and cofinanced from tax revenues on the basis of the budget adopted by the Saxon State Parliament.
