Abstract

Molten carbonate fuel cell (MCFC) has attracted much attention as a large-scale civil power generation device. However, there are some defects in MCFC. The cathode material NiO will dissolve slowly in high temperature molten salt electrolyte with a long time, and the metal Ni will precipitate on the surface of the cathode and form a bridge with the metal Ni of the anode material, thus resulting in short circuit of the battery. Experiments show that the service life of batteries can be improved by using new rare earth electrode materials and changing the composition of carbonate electrolyte.
