abstract = {This work is focused on La0.6Sr0.4CoO3-δ (LSC) infiltrated
La0.58Sr0.4Co0.2Fe0.8O3-δ (LSCF) oxygen electrode for high
temperature steam electrolysis aimed at efficient hydrogen
production. In this respect, first the chemical and
structural stability of both LSCF and LSC materials are
investigated as a function of temperature under air and
oxygen. The electrochemical performance of LSC infiltrated
LSCF oxygen electrode is then investigated for steam
electrolysis and compared with conventional LSCF electrode.
The symmetrical half-cell as well as single cell containing
LSCF oxygen electrode with and without LSC infiltration are
characterized using electrochemical impedance spectroscopy
in the temperature range 700–900°C. It is observed that
the symmetrical cell as well as single cells with LSC
infiltrated LSCF electrode performs better than the
conventional LSCF electrode. The degradation experiments
were performed with the symmetrical cells under
polarizations. Post-test analysis using SEM-EDX was
performed to investigate the changes of electrode and
electrode/electrolyte interface microstructures},
