Abstract: A cell voltage measuring connector of a fuel cell stack maintains a locking state that a locking protrusion of a CPA is inserted into a lock home of a separation plate terminal in order to prevent the connector from being separated from a separation plate of the stack. As it has a structure that connection points of a connection piece of a connection terminal is overlapped with each other based on a contact line, the reliability of the product is increased even when the thickness of the separation plate becomes less than 0.1��according to a weight lightening trend of a fuel cell. In addition, when the connector needs to be separated for component replacement, it can be easily separated by inserting an end of a separation tool into a locking release hole of the CPA by using the tool and lifting up it to release the locking of the CPA.
