摘要
The invention relates to a fuel cell comprising a polymer electrolyte membrane, two gas diffusion electrodes and two electrically conductive plates. An edge element is provided in the transition area between (1) the perimeter of the membrane arrangement, the first gas diffusion electrode and the second gas diffusion electrode and (2) the first and second plates. The invention is characterised in that at least one of the components, i.e. (1) the edge element, or (2) the plate in the marginal strip comprises a recess in at least one point in transition area between the edge element and at least one of the plates. The recess represents a local reduction of the thickness of the related component measured rectangularly in relation to the plane of extension of the membrane in such a manner that a flow gateway is formed.
