Abstract
The present invention provides a polymer electrolyte fuel cell stack that includes an inlet manifold that distributes supplies of the gaseous fuel, the oxidant gas, and cooling water in a sequence of lamination from a unit cell on one end of the cell laminate to a unit cell on the other end of the cell laminate and an outlet manifold that discharges exhausts of the gaseous fuel, the oxidant gas, and the cooling water in an inverted sequence of lamination from the unit cell on the other end of the cell laminate to the unit cell on the one end of the cell laminate. This configuration actualizes a small-sized, compact fuel cell stack.
