Centre for Microscopy, Characterisation and Analysis, The University of Western Australia, Perth, WA 6009, Australia Bismuth based oxide has excellent ionic conductivity and fast oxygen surface kinetics and shows promising potential as highly active electrode materials in solid oxide cells (SOCs) such as solid oxide fuel cells (SOFCs) and solid oxide electrolysis cells (SOECs). However, the low melting temperature and high activity of bismuth based oxides severely limit their wide applications in SOCs. Herein, we successfully synthesized 40wt% Er0.4Bi1.6O3 decorated La0.76Sr0.19MnO3+δ (ESB-LSM) electrode via a new gelation method and directly assembled on Ni-yttria-stabilized zirconia (Ni-YSZ) cermet supported YSZ electrolyte cell without the conventional high temperature pre-sintering step. ESB decoration substantially enhances the electrocatalytic activity of LSM electrode for the oxygen reduction/evolution reactions (ORR/OER). A YSZ electrolyte cell with directly
