The supply of energy and the protection of the environment have been two of the most important problems to have affected mankind in recent decades.The waste management is become a very crucial environmental problem in the world, due to the ever increasing amount of waste material, domiciliary and industrial, generated. The main strategies for the waste management are the protection of the environment and used to produce energy.
Lignin, the second most abundant component besides cellulose in biomass. In this study, lignosulfonate, is used as fuel in the solid oxide fuel cell to produce a power and heat, which is a byproducts from the wood pulp using sulfite pulping. To enhance the performance and conductivity of the biomass based fuel cell, the lignin was treated with hydroxides (Li/K) and chlorides (Fe2Cl3) at different temperature 200 -500 °C. The maximum obtained power density was about 20 mW/cm2. And the calculated electrical efficiency of the cell was about 30%. Also, this kind of biomass fuel was used in single component fuel cell and results were compared with three components fuel cell. The phase analysis, microstructure and conductivity of lignin was analysed by XRD, SEM and AC impedance technique. It has been concluded that a sulfonated lignin from waste of the paper industry can be used as a energy
sources with fuel cell operation.
