Abstract
Conventional Ni-cermet anodes show problems for the stability due to carbon coking or Ni coarsening etc.. Perovskite oxides are good candidates as an alternative anode. Electro-catalytic nanoparticles such as Ni can be produced using exsolution method or produced in oxide anodes after exposure to reducing atmosphere. In this study, we have used LSTN (La0.2Sr0.8Ti1-xNixO3-ä) as an alternative anode and investigated its electrochemical performance. Impedance spectra and power measurement of the cell with the exsolution anodes have shown the improved performance of LSTN anode in hydrogen and methane fuel.
