Monitor connection of fuel cell stack

Abstract

A fuel cell stack is constructed by laminating together unit fuel cells (1) each comprising an anode separator (7) and a cathode separator (8) sandwiching an MEA (13). The cathode separator (8) comprises on the outer circumference thereof outward projections (28) and (29) to which two terminals (91) of a voltage monitor (92) that monitors the voltage of a specific unit fuel cell (1) are connected. One of the terminals (91) is connected to the outward projection (28) of one cathode separator (8), while the other terminal (91) is connected to the outward projection (29) of another cathode separator (8). The outward projections (28) and (29) to which the terminals are connected do not overlap in the lamination direction of the unit fuel cells (1), and therefore an environment in which short-circuits are unlikely to occur between the terminals due to vibration or shock is obtained.
