The Investigation of Electrolytic Properties of Silicon Carbide for Fuel Cell

Abstract

This report is devoted to the synthesis of silicon carbide based composite as an electrolyte material for fuel cell. As fuel cell is an efficient device due to its clean energy production. To enhance the efficiency of such type of clean energy devices an efficient electrolyte material is required for its proper working. Silicon carbide is well known because of semiconductor and excellent potential in energy devices due to its better electrical and mechanical properties. It has maximum avalanche breakdown, best thermal conduction, non-oxide behavior, high melting point. In this research project Si-C composite was synthesized by solid state reaction. To study the structural properties of the synthesized samples XRD has been carried out and find out the crystallite size average 28.069nm. Through 4-probe method measured its electrical conductivity which was 0.4Scm-1at 700oC. Then fabricate three-layer pellet like device for fuel cell. Using SiC as electrolyte material, and LNCZ as electrode material. By providing hydrogen as a fuel measure electrochemical behavior of cell. The highest power density was 36 mWcm-2, and maximum 0.68V open circuit voltage.
