Specifically, an alternate solid-state processing techniqueelectrode infiltrationwould be better suited for fabricating stable yet porous perovskite-based electrodes for improved performance at intermediate temperatures . Using infiltration, the electrode's adherence could be facilitated by sintering at a lower temperature e.g., 900°C, thus eliminating the possible phase separation observed at 1200°C for SFO and any other interactions between the zirconium-based electrolyte and novel perovskite combinations.
