Abstract
In a fuel cell stack (1), a connection region SR in which a protrusion (67) of a current collecting plate (9) and a second output terminal (15) are electrically connected is formed within a belt-like range, namely, a connectable range SKH, between a first tangential line L1 tangential to the circumference of one through hole (10c) and a second tangential line L2 tangential to the circumference of the other through hole (10d). Therefore, since the flow of electric current generated in the fuel cell stack (1) is unlikely to be obstructed by the through holes (10), electric current is easily supplied to the second output terminal (15) from a current collecting section (65) of the current collecting plate (9) through the protrusion (67). As a result, a voltage loss is small, thereby improving the performance of the fuel cell stack (1).
