Die bekannten Vorrichtungen zur Veranschaulichung von Brennstoffzellen sind lediglich auf die technische Durchführbarkeit hin optimiert worden. Soll eine Brenn­ stoffzelle präsentiert werden, so gilt es, die Aufmerk­ samkeit des Betrachters zu wecken.The known devices for illustrating Fuel cells are only technical Feasibility has been optimized. Should a focal attention should be paid to the fabric cell to awaken the obedience of the viewer.

Aufgabe der Erfindung ist die Schaffung einer weiteren Vorrichtung zur Veranschaulichung von Brennstoffzellen, die in verbesserter Weise das Interesse des Betrachters zu wecken vermag.The object of the invention is to create another Device for illustrating fuel cells, which improves the viewer's interest can wake up.

Die Aufgabe wird durch eine Vorrichtung mit den Merkma­ len des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltun­ gen ergeben sich aus rückbezogenen Ansprüchen.The task is accomplished by a device with the characteristics len of claim 1 solved. Advantageous design conditions result from related claims.

Bei der anspruchsgemäßen Vorrichtung ist die Brenn­ stoffzelle Bestandteil eines Miniaturbootes oder als Miniaturboot ausgestaltet. Ein Miniaturboot entspricht einem Boot bzw. einem Schiff im Format eines Spiel­ zeugs. Dieses Miniaturboot wird im folgenden Boot ge­ nannt.In the device according to the claims, the burning is fabric cell part of a miniature boat or as Miniature boat designed. A miniature boat corresponds a boat or a ship in the format of a game stuff. This miniature boat is used in the next boat called.

Das Boot weist Mittel auf, um die Flüssigkeit, in der das Boot schwimmt, dem Boot zuzuführen, anschließend in Wasserstoff bzw. Protonen umzuwandeln und mit Hilfe des Wasserstoffs elektrische Energie zu erzeugen. Ferner sind Antriebsmittel für das Boot vorgesehen, die das Boot in der Flüssigkeit fortbewegen. Die durch die Brennstoffzelle erzeugte Energie wird mittelbar oder unmittelbar für die Fortbewegung des Bootes eingesetzt.The boat has means to hold the liquid in it the boat swims to feed the boat, then in Convert hydrogen or protons and with the help of To produce hydrogen's electrical energy. Further  propulsion means are provided for the boat that the Move the boat in the liquid. The through the Fuel cell generated energy is indirect or used directly for the movement of the boat.

Besteht die Flüssigkeit aus Wasser, so wird das Wasser zunächst einem Elektrolyseur zugeführt. Mit Hilfe von zum Beispiel Solarenergie wird das Wasser im Elektroly­ seur zersetzt. Der Wasserstoff wird der Brennstoffzelle zugeführt. Der mit der Brennstoffzelle erzeugte Strom kann unmittelbar zur Fortbewegung des Bootes einge­ setzt werden. Der Strom dient zum Beispiel dem Betrieb einer Antriebseinrichtung für das Boot, zum Betrieb des Elektrolyseurs oder einer Fernsteuerung zur Lenkung des Bootes.If the liquid consists of water, the water becomes first fed to an electrolyser. With the help of for example solar energy becomes the water in the electroly seur decomposes. The hydrogen becomes the fuel cell fed. The electricity generated by the fuel cell can be used immediately for locomotion of the boat be set. The electricity is used, for example, for operation a drive device for the boat to operate the Electrolyser or a remote control for steering the Boot.

Schwimmt das Boot in einem flüssigen Brennstoff wie ei­ nem Methanol-Wasser- oder Ethanol-Wasser-Gemisch, so wird die Flüssigkeit zunächst einem Mittel zugeführt, das das Gemisch in Wasserstoff umwandelt. Der Wasser­ stoff wird anschließend der Brennstoffzelle zugeführt. Die Brennstoffzelle erzeugt Strom. Die durch die Brenn­ stoffzelle bereitgestellte elektrische Energie dient mittelbar oder unmittelbar der Fortbewegung des Bootes.The boat floats in a liquid fuel like egg nem methanol-water or ethanol-water mixture, so the liquid is first fed to an agent which converts the mixture into hydrogen. The water substance is then fed to the fuel cell. The fuel cell generates electricity. The by the focal electrical energy provided indirectly or directly the movement of the boat.

Wird eine Direkt-Methanol-Brennstoffzelle eingesetzt, so wird das Methanol-Wasser-Gemisch direkt der Brenn­ stoffzelle zugeführt. Das Ethanol-Wasser-Gemisch ist aus gesundheitlichen Gründen dem Methanol-Wasser-Ge­ misch vorzuziehen.If a direct methanol fuel cell is used, so the methanol-water mixture becomes the distillery fuel cell supplied. The ethanol-water mixture is for health reasons the methanol water Ge mixed preferred.

Das Besondere an dieser Art der Präsentation einer Brennstoffzelle ist, daß die Flüssigkeit in zweifacher Hinsicht zur Fortbewegung des Bootes benötigt wird. Er­ stens kann sich ohne Flüssigkeit kein Boot bestimmungs­ gemäß fortbewegen. Zweitens wird die Flüssigkeit zur Bereitstellung von Energie vorgesehen, die zur Fortbe­ wegung des Bootes eingesetzt wird. Derartige Besonder­ heiten sind regelmäßig geeignet, Aufmerksamkeit zu er­ regen. So wird das Interesse und die Neugier geweckt. Ist die Neugier geweckt, so wird ein Mensch regelmäßig motiviert, sich das Gebotene eingehender zu betrachten und das Funktionsprinzip zu durchdenken.The special thing about this type of presentation Fuel cell is liquid in two With regard to the locomotion of the boat. He Mostly, no boat can determine itself without liquid  move according to. Second, the liquid becomes Provision of energy provided for the Fortbe movement of the boat is used. Such special units are regularly apt to attract attention rain. This awakens interest and curiosity. If curiosity is aroused, a person becomes regular motivates to take a closer look at what is on offer and to think through the principle of operation.

In einer vorteilhaften Ausgestaltung der Erfindung wer­ den aus der Brennstoffzelle austretende Gase zum An­ trieb des Bootes mittelbar oder unmittelbar genutzt. Insbesondere werden die Gase zum Beispiel parallel zur Flüssigkeitsoberfläche in die Flüssigkeit so eingelei­ tet, daß hierdurch das Boot infolge eines Rückstoßes angetrieben wird.In an advantageous embodiment of the invention, who the gases emerging from the fuel cell drive the boat used indirectly or directly. In particular, the gases are parallel to, for example Soak the surface of the liquid into the liquid tet that hereby the boat due to a recoil is driven.

In einem Ausführungsbeispiel weist eine Direkt-Ethanol- Brennstoffzelle die Form eines Bootes auf. Anodenseitig befindet sich der Bootsrumpf. Die Kathodenseite befindet sich oberhalb der Flüssigkeitsoberfläche. Die Gewichtsverteilung im Boot ist so, daß der Rumpf des Schiffbugs tiefer in der Flüssigkeit liegt, als der Rumpf des Schiffhecks. Das anodenseitig entstehende Gas tritt unterhalb des Bootes in die Flüssigkeit ein. Da der Bug des Bootes tiefer im Wasser liegt als das Heck, sorgt der Auftrieb des Gases für eine Vorwärtsbewegung des Bootes.In one embodiment, a direct ethanol Fuel cell in the shape of a boat. Anode side is the boat hull. The cathode side is located above the surface of the liquid. The Weight distribution in the boat is such that the hull of the Schiffbugs lies deeper in the liquid than the Hull of the ship's stern. The gas generated on the anode side enters the liquid below the boat. There the bow of the boat is lower in the water than the stern, the buoyancy of the gas ensures a forward movement of the boat.

Als Flüssigkeit ist insbesondere ein Ethanol-Wasser-Ge­ misch vorgesehen. Durch den Vortrieb gelangt das Etha­ nol-Wasser-Gemisch aufgrund einer entsprechenden Bau­ weise in die Brennstoffzelle.In particular, an ethanol-water mixture is the liquid mix provided. The etha gets through the propulsion nol-water mixture due to a corresponding construction wise in the fuel cell.
