ABSTRACT:
A cell voltage measurer of a fuel cell stack and a fuel cell system using the same, the cell voltage measurer including a plurality of terminals electrically connected to a plurality of separators of the stack, respectively; and a plurality of wiring lines coupled to at least one of a plurality of fastening mechanisms and electrically connected to the plurality of terminals, respectively. With this configuration, at least one of the wiring lines is blocked or prevented from being short-circuited by heat generated in the fuel cell stack, and has a sample structure to ease an wiring operation. Since the cell voltage of the fuel cell stack is stably measured to thereby measure (or check) the deterioration of a certain cell (or cell unit), the fuel cell stack is blocked or prevented from being suddenly stopped due to excess deterioration of the certain cell (or cell unit).
