ABSTRACT:
The present invention provides a cell voltage measuring device for a fuel cell comprising: a contact region provided on or in a separator forming the fuel cell; and a terminal contacting the separator at the contact region to measure cell voltage of the fuel cell, wherein the contact region is defined by a groove formed in the outer periphery of the separator, and wherein, in a state in which the terminal is inserted into the groove and contacts the separator, the entire area of the cross-section of the terminal perpendicular to the longitudinal axis thereof at a contact point is disposed in the groove. Accordingly, contact between the terminal and the separator can be preferably retained.
