Summary:The invention relates to a single cell assembly for a fuel cell stack having a framed membrane electrode assembly which comprises an electrochemically active region having two gas diffusion layers and a catalyst-coated membrane which are glued to a frame, with a bipolar plate which has flow-distributing and flow-guiding elements in a flow region corresponding to the electrochemically active region, wherein in an edge region of the bipolar plate surrounding the flow region, on at least one of its surfaces, a sealing groove for receiving a seal between the frame and the bipolar plate extends around the flow region. The single cell assembly according to the invention is characterized in that on at least one surface of the bipolar plate, between the sealing groove and the flow region, a receiving groove for a connection region between the frame and the membrane electrode assembly is arranged.
