Abstract
A high temperature fuel cell has a planar substantially centrally symmetrical structure. It includes an electrochemically active plate and an interconnector formed as an air heat exchanger. The air infeed positions are arranged at the periphery of the cell. The interconnector is built up in three layers: the middle layer consists of a plate which has at least approximately the same thermal expansion as the electrochemically active plate, and the side layers are formed of metal sheets which are substantially thinner than the plate of the middle layer. The metal sheets have a relief-like structure and are firmly connected to the middle plate via a plurality of contact positions. The metal side sheets are designed for a direct contact with the electrochemically active plate and the corresponding plate of a neighboring cell.
