Propane-fed Solid Oxide Fuel Cell Based on a Composite Ni-La-CGO Anode Catalyst
A composite Ni-La-Ce0.8Gd0.2O2 catalyst was investigated for the autothermal reforming of propane. A stable performance was recorded during a 100 h endurance test with a syngas yield of 85% at 800 degrees C. The catalyst was also investigated as anode for the direct utilization of propane in solid oxide fuel cells (SOFCs). This catalyst appeared less affected by carbon deposition during SOFC operation than conventional Ni-cermets.
