Argonne National Laboratory is developing molten carbonate electrolyte compositions which have minimal segregation in the individual fuel cell and cell stack under an electric field. The approach is to characterize Li-Na carbonate mixtures in terms of their segregation properties in an electric field and, if necessary, to modify the observed segregation by adding Ba and Ca carbonates. Both non-segregating properties and MCFC test-cell performance show improvement as the lithium content is modified, up or down, from a baseline of 52/48 Li/Na. Results of gasket strip (20 V) screening studies, as well as those from cell tests, will be discussed.
