  • the air flow around the electrode is a cathode and the other fuel-flow around electrode serves as an anode.
  • the object of the invention is therefore to eliminate the disadvantages of the prior art and to provide a tubular fuel cell, by means of which a higher power generation capacity per volume of a fuel cell assembly can be achieved.
  • the fuel cells and the fuel cell assembly should be safe in operation and cost little.
  • the tubes should be easy to produce. This is achieved with the features of claim 1, and the independent claims 7 and 9 according to the invention. Advantageous developments can be found in the dependent claims.
  • the invention relates to a fuel cell having a hollow cylindrical tube with a cylinder base surface and functional layers applied to the tube, which are divided into at least two segments, wherein a first functional layer anodic properties, a second functional layer cathodic properties and one the functional layer separating third functional layer has electrolytic properties, wherein the tube is aligned transversely to a gas flow, and wherein the cylinder base surface of the tube has a long axis and a short axis, wherein the short axis is aligned transversely to the gas flow, and wherein the segments separating isolations are aligned along the long axis aligned longitudinally of the tube.
  • Both the long and the short axis are geometry axes. These therefore only describe the extent of the cylinder base area in different directions. It is advantageous that the surface of the fuel cell with the same volume can be increased by the cylinder base area with a long axis and a short axis. Thus, the overall surface area of a fuel cell assembly may be large relative to its volume. Furthermore, the dynamic pressure upstream of each fuel cell can be low, since the short axis aligned transversely to the gas flow can form a small end face. At the same time, the gas flow must be deflected less strongly to the fuel cells and turbulence can be avoided. Accordingly, little energy would have to be expended for the generation of the gas flow, or the distances between two fuel cells could be made small. Thus, a high power generation performance is achievable with a fuel cell assembly having such fuel cells.
  • the insulation is arranged on the long axis.
  • the surface of the fuel cell directed towards the gas flow is thus subjected to less thermal loading and the insulation on the surface away from the gas flow lies in the zone in which the gas flow breaks off and a worse combustion would occur anyway. In this way, the remaining large and aligned along the gas flow surfaces can be flowed around particularly evenly.
  • the tube itself forms one of the functional layers and performs the function of a cathode or anode. As a result, the subsequent application of one of the functional layers can be avoided and the production costs can be reduced. If the tube forms a functional layer, the insulation should be used for the segmentation of the Functional layers separate the entire tube into two parts. For this purpose, the insulation could be incorporated directly into a sintered blank during production and sintered together.
  • An embodiment of the invention provides that the cylinder base surface of the tube is oval-shaped. This can have a positive effect on the flow resistance of the fuel cell. Especially small radii in the region of the intersection of the long axis and the tube are suitable for reducing the flow resistance. In this way, almost the entire surface of the fuel cell can be uniformly flowed around by the gas stream. Only a small end face, which is aligned in the direction of the gas flow, then forms a dynamic pressure surface. The current break on the side facing away from the gas flow side can be done very late, so that here as well as possible a large surface area can be flowed around by the gas stream. The round shapes are also less prone to thermal stress.
  • the cylinder base surface of the tube is formed elliptical.
  • This special oval shape offers a particularly good flow resistance.
  • elliptical fuel cells can be tightly packed. In this case, thermal cycling can be very well tolerated, since an ellipse is constructed mirror-symmetrically in different axes and has round shapes.
  • the cylinder base of the tube with rounded corners. Apart from the radius of the corners, in each case two sides are parallel to one another in such an embodiment.
  • the surface of the functional layers may be particularly high in such a configuration in relation to the volume of the fuel cell assembly.
  • the long axes of two adjacent fuel cells are aligned parallel to each other, the flow cross-section between them can be designed to be constant. Gas deflections are so avoidable and the flow resistance is correspondingly low.
  • the entire surface can be flown around at approximately the same flow velocity, so that the combustion can be very uniformly distributed over the surface.
  • the flat surfaces of the tube can also be particularly easily printed, whereby the manufacturing cost of the functional layers can be kept low.
  • Another embodiment would be to increase the radii of the rounded corners so much that the lying on the long axis sides of the tube have a semi-circular cross-section. As a result, the flow resistance of the tube can be reduced.
  • the long axis of the cylinder base of the tube is twice to six times as long as the short axis. Even with a length ratio in which the long axis is twice as long as the short axis of an elliptical cylinder base area, a necessary base area for an equally efficient fuel cell arrangement can be reduced by approximately 23%. Among other things, this is due to the fact that the flow resistance for the gas flow in this range of aspect ratios improves the most, so that the distances between the fuel cells can be reduced and / or the own power consumption can be reduced to generate the gas flow.
  • the flow resistance could be arranged on the downstream side of the tube a downstream tail with a cross section of a drop tip on the gas stream.
  • the gas flow does not break off, but can be conducted almost over the entire surface of the tube.
  • less turbulence arises in the flow direction behind the tube, so that the flow resistance is low. This can also increase the power generation capacity of a fuel cell arrangement equipped with such fuel cells.
  • the invention further relates to a fuel cell arrangement having at least four fuel cells, wherein each fuel cell has a hollow cylindrical tube with a cylinder base surface and functional layers applied to the tube, which are subdivided into at least two segments, wherein a first functional layer has anodic properties, a second functional layer cathodic properties and a second functional layer said third functional layer separating said two functional layers has electrolytic properties, the tube being oriented transversely to a gas flow, and wherein the cylinder base surface of the tube has a long axis and a short axis oriented perpendicular thereto, the short axis being oriented transversely to the gas flow, and wherein the segments separating isolations are arranged on the long axis aligned along the tube, and wherein the tubes of the fuel cells have a first end and a second end, and wherein the tubes with the first end are arranged in a plane and the second ends of the tubes lie on the same side of the plane.

  • the fuel cells are all arranged parallel to one another.
  • Particularly favorable for this purpose is an arrangement of the fuel cells perpendicular to this plane.
  • Such a fuel cell arrangement enables a high density in the nesting of the fuel cells, in particular because of the selected cylinder base area.
  • the imaginable, achievable surface of the fuel cells per volume is so particularly high. Accordingly, the power generation performance of such a fuel cell assembly per volume may be high.
  • the electronic connections can be easily realized. Namely, all anodes and cathodes can be connected in a plane with electrical conductors.

Through this opening, for example, first a core line lead to just before the closed second end of the fuel cell. Gas flowing from the core conduit into the interior of the fuel cell may then be diverted at the closed second end of the fuel cell and directed between the core conduit and the tube toward the opening at the first end. Ideally, this is the closed second end designed at least inside dome-shaped. Thus, the gas can be deflected with low flow resistance. In addition, thermal stresses are well tolerated.
