<P>PROBLEM TO BE SOLVED: To easily detect whether or not misalignment has occurred at laminating position of fuel battery cells when a plurality of pieces of the fuel battery cells are laminated. <P>SOLUTION: A misalignment detecting device 30 of the fuel battery cells in a fuel cell stack has detecting means 50 which are arranged on both sides along the face direction of the laminated fuel battery cells 20 and freely brought into contact with end faces 20a of the outer peripheries of the fuel battery cells, has a floating mechanism 60 which makes the detecting means advanced/retracted to/from the end faces of the fuel battery cells, and has a controller 70 which determines whether or not the misalignment has occurred at the laminating positions of the fuel battery cells based on contact/non-contact between the detecting means and the end faces of the fuel battery cells. The controller determines that the position shifts have not occurred at the laminating positions of the laminated fuel battery cells when the detecting means and the end faces of the fuel battery cells are in contact, and that the position shifts have occurred at the laminating positions of the laminated fuel battery cells when the detecting means and the end faces of the fuel battery cells are not in contact. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
