ABSTRACT:
A molten carbonate type fuel cell with a stabilized battery characteristic over a long period of time by replenishing the electrolyte which has been consumed, and maintaining the electrolyte at a consistent composition, the fuel cell carrying, on at least one of the electrolytic layer at its side of the air electrode, the air electrode per se, and the structural members of the air electrode side gas chamber, a lithium-containing composite oxide which brings about chemical reaction, when a ratio of lithium (Li) to potassium (K) in the electrolyte reduces, to produce Li.sub.2 CO.sub.3 due to change in the ratios between lithium and other elements, during a period when the Li/K ratio between lithium and potassium in the electrolyte comprising mainly Li.sub.2 CO.sub.3 and K.sub.2 CO.sub.3 varies from 40/60 to 70/30 at a temperature range of from 600.degree. C. to 700.degree. C. in a gas atmosphere of the air electrode side.
