OPERATION CONDITIONS FOR DIRECT HYDROCARBON SOLID OXIDE FUEL CELLS

摘要

The present invention relates to a method for operating a solid oxide fuel cell having a cell structure of a cathode, an electrolyte, and an anode integrated; including nickel oxide as an anode; and conducting direct internal reforming busing hydrocarbon fuel. The method for operating a direct internal reforming solid oxide fuel cell comprising the steps of: reducing the anode to metal by supplying hydrogen to the anode; and supplying hydrocarbon fuel while observing a change in cell potential during the reduction process when the cell potential reaches an equilibrium value. The supply flow of the hydrocarbon fuel is adjusted by monitoring the supply flow while a preset amount of flow is being supplied so that continuous internal reforming can be conducted.
