LiCo Dual‐Doped Ceria‐Based Composite as a Promising Low‐Temperature Electrolyte for Metal‐Supported Solid Oxide Electrolyzers

ChemSusChem, EarlyView.
Enhanced sinterability and ionic conductivity are achieved with Li and Co dual‐doped GDC electrolytes for metal‐supported solid oxide electrolyzers. The optimized sample shows 2.17 × 102 S cm1 at 750 °C, which typically approaches the superionic solid electrolyte conductivity ranges. A tubular cell fabrication and analysis demonstrated its potential as
