brennstoffzellenstapel with solid electrolytes and their arrangement

摘要

Portable fuel cell arrangement comprising fuel cells in the form of discs for axial layering in a stack which is fixed by a tie rod, wherein the fuel cell has an opening to hold the tie rod and to form an inlet for a first gas, and comprises: a high-temperature ceramic electrolyte or a low-temperature polymer electrolyte; a porous cathode layer or a porous anode layer on each side of the electrolyte; a gas-permeable substrate having channels for carrying gases; a small separating plate located at least partially on the first surface of the substrate a large, separating plate which is located on the second surface of the substrate and comprises means for carrying gases in a controlled manner. The large separating plate may comprise means for carrying gases run along continuous lines, have no branches and do not run in the radial direction or in the tangential direction, and described by the formula
