The invention discloses a single cell detecting terminal for a fuel cell, which uses a flexible printed circuit board as a detecting terminal board, wherein the flexible printed circuit board is provided with conductive terminals which are in one-to-one correspondence with anode of each single cell in a fuel cell stack, and is pressed on anodes of the fuel cell stack by a pressure plate, so as toenable each anode electrically contacted with a conductive terminal which is also provided with an output terminal for connecting a voltage collection device. The detecting terminal has excellent deformation and stress adsorbing capability.
