Abstract
Symmetrical Solid Oxide Fuel Cell has identical electrode material on both electrodes, of which the most outstanding advantage is the ability to remove the deposited carbon and other deposits from anode. Owing to the working conditions of electrodes, there are more requirements for electrode materials than normal ones. In this study, we evaluate the traditional cathode material PrNi0.4Fe0.6O3-δ as a symmetrical solid oxide fuel cell electrode material. Unstable as most traditional cathode materials are in fuel gas, however, the result here exhibits PrNi0.4Fe0.6O3-δ has good performance. The peak power density of the cell with PrNi0.4Fe0.6O3-δ electrode in wet methane at 800 °C is 663 mWcmâ2 with observable decomposition on anode. After switching the fuel gas on anode to air, the structure recovers quickly. In terms of the recyclable performance, PrNi0.4Fe0.6O3-δ seems suitable for symmetrical solid oxide fuel cell.
