Abstract
An interconnect for a fuel cell is made of pressed metal sheet. The interconnect integrates inlets and outlets, flow distributing inlet and outlet-zones seal surfaces and flow paths on both sides of the interconnect all formed and defined by discrete point or oblong protrusions made by the deformation of the sheet. A protrusion on one side of the interconnect corresponds to an indentation on the other side, but since the interconnect consists of three levels, the first side of the interconnect can be designed substantially independently of the second side.
