EVALUATION OF ELECTROLYTE MIGRATION IN MO LTEN-CARBONATE FUEL-CELL BYA MULTIELECTRODE TYPE CELL-II

The electrolyte migration was investigated using a multi-electrode typ e cell having 9 electrodes separately located on the same insulator wi th a common electrolyte plate(1)). The resistance change tvas found to be useful for understanding the electrolyte migration. In this report , we measured the time of electrolyte movement by using small-sized ce ll (416 cm(2)). As a result, the time of electrolyte movement provided by this method was almost same as a value provided by the penetration rate measurement method(2)). And a profile of fuel gas density in the electrode plane was analyzed.
