Hydrogen Production: 3D Self-Architectured Steam Electrode Enabled Efficient and Durable Hydrogen Production in a Proton-Conducting Solid Oxide Electrolysis Cell at Temperatures Lower Than 600 °C (Adv. Sci. 11/2018)

In article number 1800360, Dong Ding and co-workers report a self-architectured ultraporous 3D electrode for steam electrolysis at intermediate temperatures. The proton-conducting electrolysis cell using this steam electrode demonstrates highly efficient and durable hydrogen production below 600 °C, which is attributed to improved mass transfer and increased active reaction area, as well as the electrode reconstruction under operation conditions.
