    Abstract: PURPOSE: Provided is a process for producing a LiCoO2 coated air-electrode for a molten carbonate fuel cell(MCFC), which can prevent NiO, being a main material of the air-electrode, from dissolving in an electrolyte, therefore, can produce the air-electrode having long lifetime than the conventional air-electrode for the MCFC. CONSTITUTION: The process for producing the LiCoO2 coated air-electrode for the MCFC comprises the steps of: dissolving lithium salts and cobalt salts in water; adding a chelate agent such as polyethylene glycol to the produced water solution to produce sol; soaking a NiO electrode for the MCFC in the produced sol and forming gel on the surface of pores of the electrode; drying and calcining the electrode. And another process for producing the LiCoO2 coated air-electrode for the MCFC comprises the steps of: dissolving the lithium salts and cobalt salts in a solvent; impregnating the pores of the NiO electrode with the solution; drying and calcining the electrode.

The first circulation pipe connects the brine output port of the thermal storage and the inlet port of the brine circulation pump, and the second circulation pipe connects the brine return port of the thermal storage and the outlet port of the brine circulation pump. The control unit controls the cooling unit, brine heater, brine circulation pipe, heat exchanger and the control valve in such a manner that the circulation pump, heater and cooling unit are selectively operated during the time where electric power consumption is low so as to store heat or cold heat into the thermal storage. Thus-stored heat or cold heat is used during the time where electric power consumption is high.
