Water electrolysis technologies rely on catalysts based on metals such as Ir, Pt, Ni, La, Zr, and Yt with limited resources. To meet engineering and economic targets related to ambitious industrial scale-up at the MW and GW levels, as well as net-zero CO₂ emissions by 2050, highly performing H₂ and O₂ gas diffusion electrodes designed with low-loading catalyst layers (CLs) and stable porous transport layers (PTLs) are urgently needed.

The scope of this event is to provide the attendees relevant insights into state-of-the-art, innovative concepts and remaining challenges regarding electrode architecture for alkaline (AWE), acidic (PEMWE), and high-temperature (HTWE) technologies from both academia and industry perspective.
