The fuel cell is of planar, essentially centrally symmetrical design and has an electrochemically active plate (4) and an interconnector (1) in the form of an air heat exchanger with air supply points on its periphery. The interconnector has three layers. The middle layer is a plate (2) with at least approximately the same thermal expansion as the electrochemically active plate. The side layers (3a,3b) are metal plates and essentially thinner than the central plate. The side plates have a relief structure and are connected to the central plate at several contact points (32). They have direct contact with the electrochemically active plate and with corresp. plates in an adjacent cell. The central plate can be of composite material, at least partly of metal, metal alloy or ceramic material. |
