<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a laminated cell capable of preventing a liquid junction between unit cell layers even when the laminated cell is composed by stacking a plurality of unit cell layers by using a polymer gel electrolyte. <P>SOLUTION: In the manufacturing method of the laminated cell, a plurality of sheet-like electrodes 10 are first manufactured (step S1). Next, the electrodes are stacked by interposing gel electrode layers 4 between the electrodes (step S2); a side face of an electrode layered product 30 formed by stacking the electrodes is fitted in a die 40 matching to the side face of the layered product 30 (step S3); and a molten resin is injected into the die 40 (step S4). After the resin is hardened (step S5), the die 40 is removed (step S6). The similar processes are repeated for all the four side faces of the layered product 30 (step S7, S4-S6). Since the resin 60 is provided for all the side faces of the layered product 30, the hardened resin plays a role of a sealing member for preventing any leakage of the gel electrolyte. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
