PROBLEM TO BE SOLVED: To provide a resin frame which allows for smooth assembly work when assembling a cell by hot press.SOLUTION: A resin frame has a resin frame positioning hole 31 communicating with a separator positioning hole 41 provided in a separator 13, and a positioning pin 53 provided in a lower side jig 51 is inserted into the resin frame positioning hole 31 and separator positioning hole 41. Outer periphery of the resin frame positioning hole 31 is a first region A1, and the periphery of the first region A1 is a second region A2. The second region A2 is a thick wall part 33 that is thick in the lamination direction of the separator, and the first region A1 is a thin wall part 32 that is thinner in the lamination direction of the separator 13 than the second region A2 that is the thick wall part 33.SELECTED DRAWING: Figure 3 |
