Anode material for solid oxide fuel cell: a review

Solid oxide fuel cell (SOFC) is a technology in which chemical energy is changed into electrical energy with high efficiency and without burning fuel. A SOFC consists of electrodes and electrolytes. A single cell is not sufficient for the production of energy. Thus, single cells are staked together to produce high energy. The electrolyte lies in the middle of the anode and the cathode transport O2- ions. This eliminates the utilization of electrons in the cell via an external circuit as a transporting medium. The anode undergoes oxidation, whereas the cathode undergoes reduction. The SOFCs run between 450 and 1000 degrees C, creating just a superior grade and heat output while passionately promoting rapid electrocatalysis using metals that are common and enabling inner reorganization. In addition to O2- ion transport, SOFC works with the virtue of hydrogen for the transportation of proton. Numerous ceramic materials were developed to function effectively as anode, electrolyte and cathode materials. The material utilized as the solid electrolyte in SOFC most frequently is yttrium-stabilized zirconia (YSZ). This review presents an overview of anode materials that are acceptable for SOFCs and the main focus is given on the electrical conductivity of the anode material for SOFCs.
