Characterization of the electrochemical performance of micro-tubular solid oxide fuel cell (SOFC)

The design, fabrication, and performance characterization of a micro-tubular solid oxide fuel cell (SOFC) are presented. The cell has a yttri stabilized zirconia (YSZ), electrolyte, a nickel/YSZ cermet anode, and a lanthanum strontium manganate (LSM) cathode. The cathode compartment is supplied with atmospheric air, and the anode compartment fueled with hydrogen at a constant rate of 20 ml/min. The cell is operated for more than two hours at a constant voltage of 0.5 V at a temperature of 800°C. The operation of the cell through several thermal cycles is steady and the rate of degradation cell is low.
