<p>PURPOSE:To reduce internal resistance caused by the thinness of an electrolytic layer by inserting a fine powder layer obtained from fine powder material and organic binder between a pair of porous electrode plates and the electrolytic layer that comprise a unit battery. CONSTITUTION:A unit battery 1 for a molten carbonate type fuel cell is formed as the five-layer structure by coating a fuel electrode 3 made of a porous sintering body such as an Ni-Cr alloy and an oxidizing electrode 4 made of the porous sintering body such as Ni with fine powder layers 5 and 6 in which ceramic fine powder such as LiAlO2, organic binder, and nonaqueous solvent are kneaded and applying an electrolytic layer 7 in which mixed carbonate, carbonate holding material such as LiAlO2, organic binder, and nonaqueous solvent are kneaded to the fine powder layers 5 and 6. Then a battery main body X is formed by laminating the unit battery together with connectors 2. As a result, the intersected mixture of gas can be prevented by improving mechanical strength even if the electrolytic layer 7 is made thin.</p> |
