SOLID OXIDE ELECTROLYZER CELL INCLUDING ELECTROLYSIS-TOLERANT AIR-SIDE ELECTRODE

Abstract:

A solid oxide electrolyzer cell (SOEC) includes a solid oxide electrolyte, a fuel-side electrode disposed on a fuel side of the electrolyte, and an air-side electrode disposed on an air side of the electrolyte. The air-side electrode includes a barrier layer disposed on the air side of the electrolyte and containing a stabilized zirconia material having a lower electrical conductivity than an electrical conductivity of the electrolyte, and a functional layer disposed on the barrier layer.
