Abstract
A unit for use in a fuel cell stack, the unit comprising a porous metal support with a seal made by local fusion and—having a seal depth that extends from the upper surface of the porous metal support to at least the bottom surface of the porous metal support, and wherein the seal is positioned along the periphery of the porous metal support, the seal being impermeable to gas transported in the plane of the porous metal support.
Claims12
A method of manufacturing a unit for a fuel cell stack comprising the steps of fusing a part of a porous metal support along its periphery in a contact area into a gas impermeable seal with a seal depth, the seal depth extending from the upper surface of the porous metal support and at least through the porous metal support to the bottom of the porous metal support, wherein the porous metal support comprises an anode applied inside a porous structure in the porous metal support.
