Lignin, the second most abundant component after cellulose in biomass, is made up of about 65 percent carbon, 6 percent hydrogen, and 29 percent oxygen. It has been examined in this study as a fuel for a direct conversion into electricity. In a fuel cell, electrolyte is a core component, which plays a key role for transporting ions from anode to cathode or from cathode to anode to realize the fuel-cell function. Unfortunately so far no electrolyte studies has been reported for Lignin fuel cell. Therefore, ceria-carbonate nanocomposite electrolyte has been developed for a lignin based fuel cell. The ceria-carbonates were prepared by a co-precipitation method. In this study the conductivity composite electrolyte in both H2 and air atmosphere were studied. It has been observed that the binary carbonate (sodium/potassium) on doped ceria have higher conductivity than single carbonate on doped ceria, performance and stability of the cell.  In order to fully understand such carbonates, Raman spectra and FTIR has been performed. Microstructure   studies were   performed by X-  ray diffraction,   scanning   and transmission   electron   microscope.
