Identification of oxygen ion conductivity of Ba doped Bi0.5Na0.5TiO3 (Ba-BNT) based matrix impregnated by lithium/potassium electrolyte for molten carbonate fuel cells

Abstract

This paper presents the results of research into improving the ionic conductivity of Molten Carbonate Fuel Cell by modifying the matrix material. So far, we have succeeded in using materials such as YSZ and SDC, but we are now trying to use powders based on Ba Na and TiO2. These materials are characterized by their oxygen ion conductivity at elevated temperatures. A matrix of these materials was produced and used to build MCFCs. Based on the experiments carried out and the mathematical model of the fuel cell, the contribution of the oxygen ion conductivity to the total ionic conductivity was determined.
