Oxygen on Cnductivity and Power Density of LaGaO$_3$ Alternative Electrolytes for Ceramic Fuel Cell

ABSTRACT

La0.9Ba01Ga0.8Mg0.2O2.85 an alternative electrolyte candidate of ceramic fuel cell exhibited very high oxygen ion conductivity of>0.1 S/cm at 80$0^{circ}C$. The maximum power density of the single cell of Ni anode/La0.9Ba01Ga0.8Mg0.2O2.85 / Sm0.5CoO3-$delta$ cathode system was measured as 0.15 W/cm2 at 100$0^{circ}C$

Key words: La$_{0.9}$Ba$_{0.1}$Ga$_{0.8}$Mg$_{0.2}$O$_{2.85}$, Alternative electrolyte, Ceramic fuel cell, Oxygen ion conductivity, Power
