The lifetime of a Molten Carbonate Fuel Cell (MCFC) is reduced by the slow dissolution of the state-of-the-art lithiated nickel oxide cathode material. LiCoO 2 is considered to be an alternative cathode material by its good performance in MCFC tests. However, its dissolution rate ws not known. In this letter the dissolution properties of LiCoO 2 in 62:38 (Li:K) 2 CO 3 at 923 K are reported. The concentration of the dissolved Co 2+ ions in the molten carbonate was determined electrochemically and by ICP-AES |
