Project objective

H2-IMPACT seeks to transform anion exchange membrane water electrolysis (AEMWE) technology to enable sustainable large-scale green hydrogen production. The project addresses critical challenges, including the need for cost-effective, durable, and platinum group metal (PGM)-free electrocatalysts, as well as the stability of membrane-electrode assemblies (MEA).To overcome these issues, H2-IMPACT implements innovative catalyst synthesis methods that precisely regulate electronic structures, maximize active site density, and enhance ionic conductivity. This includes the creation of high-performance Ni-based catalysts doped with high-valent metals, confined within porous carbon supports for anode and cathode. The project also develops a groundbreaking ionomer-free MEA design with a strip-shaped hydroxyl ion conduction pathway to control local pH and enable in situ/operando analysis under real operating conditions. H2-IMPACT aims to deliver a cost-effective 5-cell AEMWE stack prototype (TRL4), targeting hydrogen production costs below €2.5/kg and a lifespan exceeding 5,000 hours. The project focuses on four core objectives: designing durable PGM-free electrocatalysts, fabricating stable ionomer-free MEA, developing high-performance AEMWE cells, and demonstrating a large-scale prototype integrated with solar energy. The project strategy combines advanced materials science and electrochemical techniques to optimize AEMWE performance.H2-IMPACT will significantly enhance my research profile by providing multidisciplinary training in hybrid catalyst synthesis, operando/in-situ techniques, and scientific communication. It will also expand my professional network in technologies, such as metal-air batteries for bifunctional air electrodes. Additionally, I will contribute my expertise in electrolyzers to the host institution. The outcomes of H2-IMPACT will support the EU's green hydrogen strategy, promote renewable energy integration, and create new economic opportunities.
