CELL VOLTAGE DETECTING DEVICE FOR FUEL CELL

摘要

PROBLEM TO BE SOLVED: To prevent a terminal of a cell voltage detecting device from slipping off from a separator of a fuel cell. SOLUTION: With the cell voltage detecting device for the fuel cell provided with a terminal 21 in contact with a separator of each unit cell and detecting cell voltage of a unit cell through the terminal 21, a contact part of the separator 14 with which the terminal 21 is in contact is constituted of a groove 16 fitted at a top edge of the separator 14, and a whole cross section orthogonal to the axis line of the terminal at the contact point is sunken in the groove 16 when the terminal 21 is in a state inserted into and in contact with the groove 16.
