5. An apparatus for manufacturing a power generating cell stack body by stacking a plurality of stack units each including a membrane electrode assembly having electrodes disposed on both sides of an electrolyte membrane and a separator wherein the membrane electrode assembly and the separator are stacked onto each other, the apparatus comprising:
a stacking table having a stacking surface on which the stack units are stacked;
a stack guide portion projecting upward from the stacking surface;
a vibration applying unit that applies vibration to the stack guide portion in a vertical direction;
a table support member connected to the stacking table and protruding downward from a back surface of the stacking surface of the stacking table; and
a floating support portion attached to the table support member and supporting the vibration applying unit in a floating manner via an elastic member,
wherein
the stack units are stacked on the stacking table wherein the stack units are caused to drop toward the stacking surface while a positioning portion provided in each of the stack units is caused to slide along the stack guide portion to which the vibration has been applied by the vibration applying unit.
