PURPOSE:To enhance the bond of an insulative sealing with a terminal plate and prevent intrusion of gas such as steam by heating under pressure those portions of a positive and a negative terminal plate which correspond to a fusion attaching resin layer, melting it stopping heating, and continuing pressurization until the temp. of the resin layer sinks below the softening point while gas is jetting, followed by cooling and solidification. CONSTITUTION:In the condition that a power generating element is accommodated between a sheet-shaped positive and a negative electrode terminal plate 1, 7 arranged facing each other, fusion attaching resin layers 2, 8 as a frame-shaped insulative sealing 17 are provided at the peripheries of the gap between these terminal plates 1, 7. Those portions of terminal plates 1, 7 which correspond to the fusion attaching resin layers 2, 8 are pressurized and heated to weld the layers 2, 8 together, and thereafter heating is stopped, and pressurization is continued until the temp. of the layers 2, 8 sinks below the softening point while gas is jetted to the layers 2, 8, followed by cooling and solidification. Accordingly even though the layers 2, 8 are contracted, the contraction force is offset by the pressurization force, and the layers 2, 8 can be maintained in good closely contacted condition. This accomplishes uniform bond of the insulative sealing 17 with the terminal plates 1, 7 to prevent intrusion of gas such as steam, and also deterioration of the power generating element can be avoided. |
