Abstract:
1. A plate element for a fuel cell stack in a monopolar arrangement, comprising: a frame region and at least one inner region which is enclosed by the frame region, a plurality of webs which extend from the frame region into the at least one inner region and define, in the at least one inner region, a flow guidance structure which is formed by recesses between the webs, such that fluid regions within anode pairs of the fuel cell stack are not separated and such that fluid regions within cathode pairs of the fuel cell stack are not separated, and at least four bore holes in the frame region, of which at least two are connected with the flow guidance structure, wherein the plate element is made as a laminate of an insulating layer and two conductive layers which embed the insulating layer as if in a sandwich, such that the anodes and cathodes within the anode and cathode pairs are electrically insulated from each other.
