Arrangement of fuel cells based on a high-temperature solid electrolyte of stabilized zirconium oxide for achieving maximum possible power

An arrangement of fuel cells based on a high-temperature solid electrolyte of stabilized zirconium oxide for achieving maximum possible power in minimum space, wherein a plurality of fuel cell elements, each consisting of a plane, flat sheet, are stacked one on top of the other and connected electrically in series in such a way that in each case the oxygen electrode of the one element is connected to the fuel electrode of the next following element by an electrically conductive component,

• wherein the stack, consisting alternately of flat fuel cells and electrically conductive components in the form of bipolar plates, is encased by channels arranged on the cross-flow principle for the feeding of the gaseous oxygen carrier and of the gaseous fuel as well as for the removal of the excess of the gaseous oxygen carrier and of the ballast gas and the removal of the excess of the fuel and of the gaseous reaction products, and wherein an oxygen-side endplate and a fuel-side endplate, with an electrical lead to the positive terminal and an electrical lead to the negative terminal, are provided, and
• wherein a plurality of plate stacks with fuel cells and bipolar plates are set up with their longitudinal axes perpendicular on the planes of the plates disposed in parallel and vertically next to one another in such a way that their outline forms a square checkerboard of plate stacks and channels in between for the gaseous media or inequilateral octagonal plate stacks and differently-sized square channel cross sections in between for the oxygen carrier and the fuel.
