Abstract
Provided is a fuel cell stack manufacturing method that can achieve a uniform pitch between fuel cells, that is, unit cells, and can increase the sealing properties between the unit cells. The fuel cell stack manufacturing method is a method for manufacturing a fuel cell stack including the lamination of a plurality of unit cells. This method includes a conveying step and a stacking step. The conveying step conveys the unit cell with its opposite ends held in a state where a pair of separators forming the unit cell vertically faces each other. The stacking step stacks in the vertical direction the plurality of unit cells with the gasket interposed therebetween. The upper and lower sides of the unit cells in the stacking step are inverted from those of the unit cells in the conveying step.
