Degradation Phenomena Compendium: A Strategic Guide for Hydrogen Innovation

The ELECTROLIFE project has made a significant breakthrough by delivering the Degradation Phenomena Compendium, now publicly available to advance innovation in hydrogen production technologies. Electrolysis technologies are categorized into two types:

  • Low-Temperature Systems: Alkaline Electrolysis (AEL), Anion Exchange Membrane Electrolysis (AEMEL), and Proton Exchange Membrane Electrolysis (PEMEL)
  • High-Temperature Systems: Solid Oxide Electrolysis (SOEL) and Proton-Conducting Ceramic Electrolysis (PCCEL)

Each technology involves unique materials and operational conditions, presenting distinct degradation challenges. The compendium provides an in-depth exploration of critical degradation mechanisms – chemical, mechanical, and physical – impacting essential electrolyser components such as catalysts, membranes, transport layers, interconnectors, and plates.

Degradation Phenomena Compendium is a vital resource for both researchers and industry professionals. By addressing the intricate challenges of electrolyser degradation, it lays the foundation for future advancements, driving the hydrogen economy forward and supporting the transition to a sustainable energy landscape.
