The performance of all solid-state battery fabricated using a protonic solid electrolyte in conjunction with different cathodes namely MnO2, PbO2 and V6O13 is studied systematically. Composite proton conducting solid electrolyte NaH2PO4:Na2HPO4 is prepared following chemical route. The proton transport number determined following both the coulometric and the emf technique are found approximately equal to unity. Particularly, the cells are tested under constant load and constant current drain conditions. Open circuit voltage of cell with MnO2, PbO2 and V6O13 cathodes is found 1.5, 1.8 and 2.22V, respectively. The short-circuit-current 1, 0.5, and 0.3mA, respectively is obtained. The complex impedance analyses of the cell before during and after the discharge are carried. The maximum current drain of the order of 200muA is achieved.
