PROBLEM TO BE SOLVED: To provide a stacking method of stack members capable of shortening a time necessary for stacking the stack members.;SOLUTION: In a first conveyance process (S11) of a stacking method of stack members, a first stack member (a single cell 111A-2) is conveyed by a conveying device to a stack stage. In a transfer process (S12), the first stack member conveyed to the stack stage is transferred to a retreat position spaced from the conveying route of the conveying device. In a second conveyance process (S13), with the first stack member retreated to the retreat position, a second stack member (a single cell 111A-3) is conveyed by the conveying device to the stack stage. In a stack process (S14), the first stack member retreated to the retreat position is transferred to the second stack member on the stack stage and the first stack member is stacked onto the second stack member in the stack stage. In a conveying-out process (S15), stack members including the first stack member and the second stack member are conveyed out from the stack stage.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
