Abstract

The elevated-temperature creep strength of several alternative cathode materials (LiFeO2 and LiCoO2, both pure and doped) for potential use in molten carbonate fuel cells was compared to the currently used Li (1-5 at%)-doped NiO. It was observed that at 1000°C, LiFeO2, LiFeO2-12.5 at% NiO, LiFeO2-9 at% MgO and LiCoO2 have a lower strength than NiO-5 at% Li2O.
