METHOD OF PREVENTING FUSED CARBONATE TYPE FUEL CELL FROM INTERNALLY SHORT-CIRCUITING BY CATHODE ELUSION

摘要

PROBLEM TO BE SOLVED: To prevent internal short circuit from being caused between a cathode and an anode by deposited nickel. SOLUTION: An anode exhaust gas line 4 connected to the outlet side of an anode 3 is connected to the inlet side of a cathode 2. A recycling blower 5 is arranged in the midway of the anode exhaust gas line 4. By recycling anode exhaust gas for supplying to the cathode 2 to control an electrodes deferential pressure so that a pressure of the anode 3 is higher than that of the anode 2, eluted nickel in an electrolyte plate is prevented from spreading to the anode side for preventing internal short circuit.
