The role of input gas species to the cathode in the oxygen-ion conducting and proton conducting solid oxide fuel cells and their applications: Comparative 4E analysis

Most of the gas species in the air entering the fuel cell through the cathode electrode is nitrogen. Nitrogen recognizes as the only reactant inside the fuel cell stack that remains unchanged during its internal chemical and electrochemical processes. Owing to this specific behavior of nitrogen, this study investigates the performance of two types of solid oxide fuel cells with different electrolytes (oxygen-ion conducting and proton conducting)...
