Disclosed is a stack welding apparatus for a redox flow battery. The stack welding apparatus for forming a stack by vibration-welding unit cells including an electrode flow frame and a membrane flow frame of a zinc-bromine flow battery including: i) a lower die supporting at least one unit cell and installed to be movable in a vertical direction; ii) an upper die disposed above the lower die and pressurizing the at least one unit cell as the lower die is lifted; and iii) a vibration source applying vibrations to the upper die to vibration-weld the at least one unit cell, wherein a plurality of divided plates are installed and fixed to bases of the lower die and the upper die corresponding to each other, and a thickness adjustment thin plate for adjusting a thickness deviation of the at least one unit cell is installed between at least one divided plate and one of the bases.
