Definitions
- the present invention relates to a fuel cell arrangement consisting of at least two individual fuel cells, wherein the individual fuel cells are not arranged parallel to each other, i. offset or arranged in shingles to each other.
- the electrical interconnection of a plurality of electrochemical cells is carried out in stack arrangements via electrically conductive layers, for example graphite plates. Often such stacked fuel cells are unsuitable for integration into particular applications because of their aspect ratio. Alternatively to this stack construction you can Arrange fuel cells in a plane.
- the electrical interconnection can then be carried out by conductive layers, wherein the anode of one cell contacts the cathode of the adjacent cells for voltage addition. This conductive
- Layers are arranged parallel to the overall structure of the planar fuel cell. As a result, the electrical connection of the neighboring cells is only possible via outward-guided contacts. This requires additional space and increases the voltage losses due to extended electrical lines and thus higher electrical resistance.
- the electrical interconnection has been solved in planar arrangements over outward contacts or with the help of angled current conductors.
- the angled current conductors are not able to compensate for changes in thickness of the fuel cell layer structure that occur during operation.
- the contact resistance between the current collector and the fuel cell electrode changes and deteriorates, thus deteriorating the output.
- a fuel cell comprising at least two individual electrochemical cells, each individual electrochemical cell being composed of at least the following constituents: a) at least one anode-side current arrester structure, b) a fuel supply, c) an electrode membrane E) comprising an anode-side electrode, a membrane and a cathode-side electrode, d) a supply possibility for the oxidizing agent, and e) at least one current collector structure arranged on the cathode side, wherein each individual electrochemical cell is electrically connected directly to at least one adjacent individual electrochemical cell is and is arranged offset with respect to the at least one adjacent electrochemical single cell.
- Essential to the invention is thus that the individual cells are connected directly to each other electrically. For example, in the case of a series-connected arrangement of individual cells, this is done by connecting the cathode of the first cell directly to the anode of the second cell.
- a direct connection is understood here to mean that the electrodes of the fuel cell preferably contact one another without further means for interconnecting the electrodes, such as, for example, cables, wires or contacts are. It is essential that the fuel cells are not arranged linearly but offset, preferably not arranged in parallel.
- Thickness variations can be compensated as with a fuel cell stack, the current arresters do not require high-precision bending and are therefore much cheaper to produce.
- the fuel cells can be glued to the current conductors via spacers. Mechanically no forces act on this bond, as is the case with angled current conductors. This makes it possible to realize a seal by gluing.
- Another advantage of the shingling arrangement is that the fuel supply channels are arranged obliquely to the installation plane of the fuel cell. As a result, the discharge of the gaseous by-products from the anodic distribution structure is supported in a passive manner.
- the fuel cells are arranged in shingled construction.
- the non-parallel arrangement of the fuel cell is designed so that they are in construction direction, ie in the direction of the vector in which the individual cells are connected, twisted or tilted to each other.
- the arrangement of the fuel cells is possible in one and / or in two dimensions.
- the at least two electrochemical individual cells are arranged in a one-dimensional manner such that the normals of the current drain structures or with the direction vector in the direction of which the individual cells are connected form an angle ⁇ which is between 5 ° and 85 ° .
- fuel cells have a structure in which the two Stromableiterstruktu- ren, which limit the fuel cell, are arranged plane-parallel to each other. This results in a more or less monolithic, cuboid structure of the individual fuel cells.
- the arrangement of the fuel cells now preferably takes place in such a way that the normals of the current collector structures of the individual fuel cells are tilted toward one another. are arranged, wherein the fuel cells are each in direct contact with each other.
- each electrochemical individual cell is connected directly in series with at least one adjacent electrochemical individual cell.
- the fuel cell contains at least three electrochemical single cells, wherein the terminal individual cells of the fuel cell are each directly electrically connected to an adjacent single cell, while the at least one arranged therebetween individual cell is each directly electrically connected with two adjacent individual cells.
- Particular embodiments of the fuel cell provide that in the case of the terminal electrochemical individual cells of the fuel cell, either the anode side or cathode side current collector structure is not connected to an adjacent individual cell, while in the case of the individual cells arranged therebetween both the anode and cathode sides arranged Stromabieiter Jardin is connected to at least one adjacent single cell.
- the one terminal electrochemical individual cell has an anode-side current-drainage structure which is not connected to an adjacent individual electrochemical cell and the other terminal electrochemical single cell has a cathode-side current-drainage structure which is not connected to an adjacent individual cell.
- a further embodiment provides that in each case both the anode side arranged Stromableiter- structure arranged between the terminal electrochemical single cell of the fuel cell electrochemical cell with the cathode side arranged Stromabieiter Modell their adjacent single cell and each arranged on the cathode side Stromabieiter Modell this single cell with the anode side arranged Stromabieiter Modell their adjacent single cell is electrically connected directly.
- the majority of the individual cells of the fuel cell are preferably integrated in a housing.
- the fuel cells are arranged in a plane in the housing, which does not run parallel to the housing walls. This is understood according to the invention to mean that the plane in which the individual cells are tilted (for example by the angle ⁇ ) does not run parallel to the housing walls in whose direction the tilting has taken place.
- the fuel cell provides that the at least two electrochemical individual cells are glued via spacers.
- the membrane-electrode units of two adjacent cells are glued to the front and back of a common Stromableiters in such a way that with the help of both sides coated with adhesive, frame-shaped spacers first, the installation space of the membrane-electrode unit is defined, secondly the connection of two membrane electrode assemblies is made with the current conductor to a common arrangement and third the arrangement so executed is sealed from the environment.
- the supply possibility for fuel as a plurality of distribution channels and / or the supply possibility for the oxidizing agent is formed as a plurality of distribution channels.
- the selection with regard to the individual cells is not subject to any general restriction, but it is advantageous if alkaline or basic planar fuel cells, in particular direct alcohol fuel cells, are used. Further advantageous embodiments provide that the individual cells are selected from the group consisting of polymer electrolyte membrane fuel cells (PEM), methanol fuel cells (DMFC), ethanol fuel cells (DEFC), ceramic fuel cells (SOFC) and / or combinations thereof.
- PEM polymer electrolyte membrane fuel cells
- DMFC methanol fuel cells
- DEFC ethanol fuel cells
- SOFC ceramic fuel cells
- Such fuel cell systems can be used in particular for the supply of electronic units whose operation must be ensured over very long periods of time and whose energy consumption is low, such as sensors from environmental monitoring, traffic measurement and control systems, GSM / GPS / GPRS navigation systems and their Combination, battery charging systems, integrated energy - supply units for applications in the electronic consumer sector, eg PDA, mobile phone, laptop, recording devices (eg Deutsche Bahn card readers, UPS, etc.), intelligent / functional housings or packaging.
- the figure shows two shingles, so tilted arranged individual cells, which are connected to a fuel cell array.
- the individual cells each have an anode side structure 1 attached to the bottom side, channels for fuel distribution 2 adjoining this current collector structure 1, a membrane electrode unit (MEA) arranged on the side facing away from the fuel distributor channels 2, comprising an anode-side electrode 6, an adjoining one
- MEA membrane electrode unit
- Membrane 5 and a cathode-side electrode 4 and a cathode-side Stromabieiter Quilt 8, followed by a plurality of oxidation channels 7 connects.
- the individual cells are connected in series, in that the current drainage structure 1, which forms the anode of the first fuel cell, is connected directly to the current drainage structure 8 of the right-hand single cell. This eliminates the need to connect the individual cells via additional aids, such as contacts, cell connectors or cables.
- the individual cells are integrated in a housing 3, so that the complete fuel cell module results as a single unit.
- the fuel cells are arranged in a manner which corresponds to a non-parallel arrangement of the fuel cells with respect to the housing (in this perspective illustration with respect to the top and bottom of the housing).
- the arrangement of the individual cells takes place in a tilted manner with respect to the housing 3.
- the angle, the normal 9 of the Stromabieiter Modell 1 and 8 with the directional vector 10, in the direction of which the individual cells are arranged consecutively includes, between 5 ° and 85 °.
