ELECTRONIC CONDUCTIVITY CONTROL IN SOFC ELECTROLYTE OF SOFC BY OXYGEN PARTIAL PRESSURE IN ANODE AND WORKING METHOD THEREOF

摘要

PURPOSE: A solid oxide fuel cell is provided to prevent leakage current by injecting a small amount of oxygen or a mixed gas of air and fuel gas and to maximize the performance of the solid oxide fuel cell. CONSTITUTION: A solid oxide fuel cell includes: an anode holding an oxidation catalyst of hydrogen gas and hydrocarbon; a cathode which is independently installed, holds a catalyst for the reduction of oxygen, and in which air is inserted; and a solid oxide electrolyte layer formed between the anode and cathode.
