- DIRECT HYDROCARBON FUELED SOLID OXIDE FUEL CELLS WITH COKING FREE ON-CELL REFORMER

摘要

The present invention relates to a solid oxide fuel cell which is directly reformed internally using a hydrocarbon fuel, comprising: a unit cell comprising a cathode / electrolyte / fuel electrode; and an on-cell reformer disposed on a fuel electrode side of the unit cell, Wherein the cell reformer is composed of an active material having catalytic ability to the hydrocarbon fuel and a lattice oxygen supplier. The on-cell reformer may be integrated into a single cell or formed in a cell structure attached to the anode chamber side. According to the present invention, even when the hydrocarbon fuel is used directly, it is possible to realize high performance of the solid oxide fuel cell, to secure the long-term driving stability by suppressing carbon poisoning, and to provide an efficient and economical solid oxide fuel cell system Can be implemented.
