Abstract:
1. A manifold insert installed in a fuel cell stack, the manifold insert being configured to form a flow field from an inlet port of fluid to an outlet port connected to the fuel cell stack, the manifold insert comprising: a plurality of distribution guides for dividing the flow field from the inlet port to the outlet port such that the fuel cell stack is divided into a plurality of regions according to a distance from the inlet port, wherein the plurality of distribution guides each have a surface that is at least partially curved such that a flow of a fluid from the inlet port to the outlet port is changed by the surface that is at least partially curved, and form a plurality of guide flow fields for guiding the fluid to the plurality of regions that are divided of the fuel cell stack such that the fluid is supplied to the plurality of regions that are divided of the fuel cell stack along the plurality of guide flow fields at different flow rates wherein the inlet port is formed along a first plane and the outlet port is formed along a second plane, the second plane substantially perpendicular to the first plane, and wherein each consecutive distribution guide of the plurality of distribution guides extends beyond its subsequent distribution guide along the second plane from an inlet port side of the fuel cell stack to an nth region of the plurality of regions.
