Research Abstract

Intermediate temperature SOFCs using apatite-type ionic conductors as a thin film electrolyte have been developed. The films of apatite-type solid electrolytes were deposited by atmospheric DC plasma spraying on the anode substrates consisting of NiO and apatite ionic conductors. Cathode materials were then screen-printed on the apatite films. The SOFCs thus obtained showed maximum power densities of 150 mW cm-1 which have been improved by optimizing the deposition conditions and the electrode compositions. Sputtering depositions of the apatite-type solid electrolytes also have been studied.
