Die vorliegende Erfindung bezieht sich auf einen Elektrolyten aus einer Ionenaustauschermembran für ein Brennstoffelement für flüssige oder gasförmige Brennstoffe. Derartige Elektrolyte sind an sich bekannt, jedoch enthalten sie einen organischen Ionenaustauscher. Der Nachteil der meist aus einem Harz bestehenden Austauscher liegt in deren geringer Stabilität und in ihrer Wärmeempfindlichkeit.The present invention relates to an ion exchange membrane electrolyte for a fuel element for liquid or gaseous fuels. Such electrolytes are known per se, however, they contain an organic ion exchanger. The disadvantage of mostly made of a resin existing exchangers is due to their poor stability and their sensitivity to heat.
Um nun hier eine Verbesserung zu schaffen, wird erfindungsgemäß vorgeschlagen, daß bei einem Elektrolyten der obigen Art die Membran aus einer Mischung eines inerten Trägermaterials mit dem Phosphat des vierwertigen Zinns oder Titans besteht. Eine derartige Membran besitzt eine hohe Stabilität. Außerdem kann sie bei Temperaturen bis zu 150° C verwendet werden, ohne beschädigt zu werden und ohne Verlust oder Veränderung der austauschenden Eigenschaften.In order to create an improvement here, it is proposed according to the invention that in the case of an electrolyte of the above type, the membrane made of a mixture of an inert carrier material with the phosphate tetravalent tin or titanium. Such a membrane has a high stability. In addition, it can be used at temperatures up to 150 ° C without being damaged and without loss or change of the exchanging properties.
Das Trägermaterial des Elektrolyts besteht vorzugsweise aus Asbest.The carrier material for the electrolyte is preferably made of asbestos.
Die Membran wird zweckmäßig in Form einer dünnen, festen und dabei biegsamen Platte durch Pressen besagter Mischung hergestellt. In einem solchen Elektrolyten ist das Ion M+ der Stromträger.The membrane is expediently produced in the form of a thin, solid and flexible plate by pressing said mixture. In such an electrolyte, the M + ion is the current carrier.
Als Brennstoffe kommen sowohl Gase wie Wasserstoff, als auch Flüssigkeiten wie z. B. Methanol in Betracht.Both gases such as hydrogen and liquids such as. B. methanol in Consideration.
Als Elektroden können erfindungsgemäß verwendet werden:According to the invention, the following electrodes can be used:
a) poröse Elektroden, besonders solche aus porösem Graphit, die mit einem Katalysator (Ruß, Platin oder Silbermoor) bedeckt sind. Diese Überzüge werden auf dem Trägergraphit mittels eines Bindemittels fixiert, das gleichzeitig die 3*> Benetzbarkeit verhindern und die Ausbildung von Dreiphasengebieten ermöglichen soll;a) porous electrodes, especially those made of porous graphite, which are covered with a catalyst (soot, platinum or silver moor). These coatings are fixed on the carrier graphite by means of a binding agent, which at the same time prevents the 3 *> wettability and enables the formation of three-phase areas;
b) andere metallisierte poröse Stoffe wie Asbest, der mit Silber imprägniert ist.b) other metallized porous materials such as asbestos impregnated with silver.

Als Ausführungsbeispiel diene die Zeichnung.The drawing serves as an exemplary embodiment.
In dieser bedeutet 1 eine positive Elektrode, die aus Stahlwolle oder einem Drahtgeflecht aus rostfreiem Stahl besteht, das mit einem Katalysator aus Cu, Ag oder Au in Pulverform bedeckt ist. 2 stellt die Brennstoffelektrode dar mit demselben Gerüst, das aber mit einem metallischen Katalysator aus der VIII. Gruppe des Periodischen Systems (wie Ir, Pd, Rh, Pt) bedeckt ist. Zwischen den Elektroden 1 und 2 liegt der Elektrolyt 3, bestehend aus einer durch Zusammenpressen erzeugten Membran aus Asbestfibern, die mit den erwähnten Phosphaten des vierwertigen Sn oder Ti imprägniert sind. Das Element wird über eine Leitung 5 mit Sauerstoff oder atmosphärischer Luft gespeist und mit Wasserstoff über eine Leitung 6. Abzugkanäle 7 und 8 sind vorgesehen, um die in den gasförmigen Brennstoffen vorhandenen Verunreinigungen abzuleiten.In this, 1 means a positive electrode made of steel wool or a wire mesh made of stainless steel Steel is covered with a catalyst made of Cu, Ag or Au in powder form. 2 represents the fuel electrode has the same framework, but with a metallic catalyst from the VIII. Group of the Periodic Table (such as Ir, Pd, Rh, Pt) is covered. Between electrodes 1 and 2 is the electrolyte 3, consisting of a membrane made of asbestos fibers produced by compression, which are impregnated with the mentioned phosphates of tetravalent Sn or Ti. The element will fed via a line 5 with oxygen or atmospheric air and with hydrogen via a Line 6. Discharge channels 7 and 8 are provided to the existing in the gaseous fuels Discharge impurities.
