Elektrolytische Zelle. Patentiert im Deutschen Reiche vom 23. Oktober 1923 ab. Electrolytic cell. Patented in the German Empire on October 23, 1923.
Gegenstand der Erfindung ist eine elektrolytische Zelle, welche, im Wechselstrom geschaltet, an beiden Elektroden eine gleichmäßige, der Zeit und dem Strom proportionale Wasserstoffentwicklung ergibt. Diese Zelle ist dadurch gekennzeichnet, daß beide Elektroden aus Aluminium bestehen und der Elektrolyt von der wäßrigen Lösung einer Aluminiumhydroxyd lösenden Substanz gebildet wird, die eine Säure oder Base sein kann. Es können demnach prinzipiell auch alle Säuren verwendet werden, doch müssen aus praktischen Gründen jene ausscheiden, welche Aluminium angreifen. Besonders gute Resultate ergeben Essig-, Salpeter- oder Chromsäure, bei deren Verwendung das ge-The invention relates to an electrolytic cell which, in alternating current switched, at both electrodes a uniform one proportional to the time and the current Hydrogen evolution results. This cell is characterized by having both Electrodes consist of aluminum and the electrolyte from the aqueous solution of a Aluminum hydroxide dissolving substance is formed, which can be an acid or base can. Accordingly, in principle, all acids can also be used, but they must for practical reasons those who attack aluminum should be eliminated. Particularly good ones The results are acetic, nitric or chromic acid.
bildete Aluminiumhydroxyd als entsprechendes Salz in Lösung geht. Bei Verwendung verdünnter Chromsäure spielt sich der elektrolytische Prozeß nach folgenden Formeln ab:formed aluminum hydroxide as the corresponding salt goes into solution. Using With dilute chromic acid, the electrolytic process takes place according to the following formulas away:
2 Al + 6 H2O = 2 Al(OH)3 + 6 H ■2 Al + 6 H 2 O = 2 Al (OH) 3 + 6 H ■
2 Al(OH)5 + 3 H2Cr2O,2 Al (OH) 5 + 3 H 2 Cr 2 O,
= Al2(Cr2O7)s + 6H2O,= Al 2 (Cr 2 O 7 ) s + 6H 2 O,
wobei dem Verbrauch von ι mm3 Aluminium
eine frei werdende Wasserstoff menge von 2,4 cm3 gegenübersteht.
Wenn die von Elektrolyten berührten Flä-where the consumption of ι mm 3 aluminum is offset by a liberated amount of hydrogen of 2.4 cm 3 .
If the surfaces in contact with electrolytes
,15 chen des Aluminiums gleich groß erhalten werden, so ergibt die Zelle bei gleichbleibender Stromstärke in der Zeiteinheit gleiche Mengen von Wasserstoff. Zur Aufrechterhaltung der- Gleichheit der Kontaktflächen.15 surfaces of the aluminum are obtained the same size, the cell results with the same Current strength in the unit of time equal amounts of hydrogen. To maintain the equality of the contact areas
so werden die Aluminiumelektroden zylindrisch oder prismatisch gestaltet und an der äußeren Boden- und der Mäntelfläche mit einer isolierenden, die Einwirkung des Elektrolyten abhaltenden Umhüllung versehen.so the aluminum electrodes are designed cylindrical or prismatic and on the outer one Bottom and shell surface with an insulating, the action of the electrolyte retarding envelope provided.
In Abb. ι der Zeichnung ist ein Ausführungsbeispiel einer der Erfindung entsprechenden, elektrolytischen Zelle schematisch im Querschnitt gezeigt. Jede der beiden im Behälter m angeordneten Elektroden η, η wird von einem Aluminiumkörper zylindrischer oder prismatischer Form gebildet, in dessen Achse der Leitungsdraht" α verlegt ist und welcher an seiner äußeren Mantel- und Bodenfläche mit einer isolierenden, von Elektrolyt nicht angreifbaren Hülle ο versehen ist. Der Elektrolyt kann von irgendeiner Aluminium nicht angreifenden Säure oder einer Base gebildet werden. Infolge der zylindrischen Form der Aluminiumelektroden n, n, welche nur an der oberen Deckfläche der Einwirkung des Elektrolyten ausgesetzt sind, wird bei gleichbleibender Stärke des durchlaufenden Wechselstromes in jeder Zeiteinheit dieselbe Wasserstoffmenge entwickelt. Die Zelle eignet sich aus diesem Grunde ganz besonders für gewisse Registrierungszwecke, zur Betätigung von Zeitschaltern u. dgl.In Fig. Ι the drawing, an embodiment of an electrolytic cell corresponding to the invention is shown schematically in cross section. Each of the two electrodes η, η arranged in the container m is formed by an aluminum body of cylindrical or prismatic shape, in the axis of which the conductor wire "α" is laid and which is provided on its outer shell and bottom surface with an insulating sleeve ο which cannot be attacked by electrolyte The electrolyte can be formed by any acid or base that does not attack aluminum. As a result of the cylindrical shape of the aluminum electrodes n, n, which are only exposed to the action of the electrolyte on the upper cover surface, the alternating current flowing through it in every unit of time For this reason, the cell is particularly suitable for certain registration purposes, for operating time switches and the like.
