To provide the manufacturing method for unit cell of fuel cell, capable of satisfactorily keeping electrical contact between a metal plate and a membrane-electrode assembly.
The manufacturing method of the unit cell of the fuel cell, having a plate-like membrane-electrode assembly and first and second metal plates 5, arranged on each side of the membrane-electrode assembly and mechanically sealing the peripheral regions of these metal plates 5 via an insulating layer has at least a process in which the first metal plate, having an erected part in the peripheral region 5a; the membrane-electrode assembly, and the second metal plate 5 are set vertically, in this order; and the erected part of the peripheral region of the first metal plate is bent inward to be caulked for sealing, and thereafter, a process working the overall shape of the unit cell, from a plane shape to an arch shape.
