Abstract

Abstract : Layered H + -SOFCs with a LN-1, LN-2 or Ni/La2 O3 catalyst layer had great cell performance for dry reforming of methane as fuel. Abstract : Catalyst layers derived from La2 NiO4, LaNiO3 and Ni/La2 O3 precursors were applied to a conventional Ni-based anode in a proton conducting solid oxide fuel cell (H + -SOFC) for the dry reforming of methane with CO2 . The phase structures, microstructures and catalytic activities of catalysts from the different precursors were systematically investigated. The cell performance and durability of a H + -SOFC with a catalyst layer (layered H + -SOFC) were examined. The layered H + -SOFC had higher cell performances than the conventional H + -SOFC. However, catalyst deactivation and degradation of the cell performance were observed as carbon deposition occurred on the catalyst layer due to CO disproportionation in exhaust gas at a high partial pressure of CO. The structure of carbon deposited on the catalysts was also investigated.
