Abstract
At the Netherlands Energy Research Foundation (ECN) two approaches to the Molten Carbonate Fuel Cell (MCFC) cathode lifetime problem are investigated. In the first approach it is tried to reduce the dissolution-rate of the state-of-the-art NiO material by means of electrolyte additives. Thusfar, a reduction of circa 50% could be obtained using alkaline-earth oxides of carbonates. The second approach is the development of alternative materials with good performance and very low dissolution-rate, suitable to replace NiO. In this respect LiCoO{sub 2} is a promising candidate. In addition to a good in-cell behavior, this material has a dissolution-rate which is almost an order of magnitude lower than that of NiO, and it has a favourable dissolution mechanism. In order to explain the significant differences in NiO, LiCoO{sub 2}, and LiFeO{sub 2} performance, porous-electrode modelling has been started. Preliminary results indicate that intrinsic materials properties, i.e. catalytic activity and electrical conductivity, play a crucial role in the observed polarization behavior. 3 figs., 2 tabs., 6 figs.
