Nanostructured anode catalyst layer for oxygen evolution reaction based on a novel thin-film architecture

ended

The transformation of energy coming from renewable sources into gas with the purpose of storage and transportation (power-to-gas) is a powerful approach for the development of new-generation secure, clean, efficient energy systems. Key step in such a process is electrolysis, which utilizes electrical current for splitting water into oxygen and hydrogen. While the present electrolysis technology (anion exchange cells) is insufficient for covering the future demands, polymer-based cells (PEMECs) represent an emerging alternative for becoming the key-enabling technology in power-to-gas systems. Thin-CATALYzER aims at making an important step towards the implementation of PEMECs at large scale by introducing an innovative paradigm based on thin-film technology for the fabrication of an efficient, durable and sustainable PEMEC anode catalyst layer. This will serve both as an end-product possessing a high level of technological readiness and as a platform for achieving new information on the fundamental reaction mechanisms. Thin-CATALYzER tackles the current limitations of PEMEC anodes as it takes advantage of a single-step physical deposition process (PLD) for obtaining a nanostructured catalyst layer with high level of purity and of noble metal utilization, optimized meso- and microstructure, to be deposited on ceramic single crystals or on a commercial support according to the needs. Besides, the project comprises a program for the professional growth of the ER by training-through-research in catalysis and related techniques and for the development of complementary skills. This will be achieved thanks to the commitment of the host institution and of the action partners (academic and industrial), which possess a highly qualified and intersectorial knowledge. Lastly, the action promotes a two-way transfer of knowledge and the development of an extended network for all the actors involved.
