Patent ID: 7964318

Claim:
A coolant manifold that is installed on a fuel cell stack so as to distribute coolant through the fuel cell stack, which is constituted by a plurality of unit cells stacked in a stacking direction and has more than one communication hole for coolant supply and at least one communication hole for coolant discharge, in which the coolant flows in an order from the communication holes for coolant supply through a plurality of the unit cells to the communication hole for coolant discharge, the coolant manifold distributing the coolant into the communication holes for coolant supply, the coolant manifold comprising: a manifold body having a manifold chamber that extends along an alignment direction of the communication holes for coolant supply, wherein the manifold body and the manifold chamber extend in a direction perpendicular to the stacking direction; and an external communication part having an external communication hole for communicating the manifold chamber with a component external to the fuel cell stack, and a center axis of the external communication hole being disposed in a non-horizontal and non-vertical position relative to a center axis of each communication hole for coolant supply.
