Nature Communications, Published online: 13 May 2026; doi:10.1038/s41467-026-72976-7 Efficient hydrogen production using water electrolysis is limited by poor electrode design and durability. Here, the authors report a tape-cast nickel–iron electrode with integrated catalytic and transport functions that delivers high current density and long-term stability through an improved architecture.
