Description
Bekanntlich haben Zellen aus Kupferjodür mit verschiedenen Metallelektroden gleichrichtende Wirkung. Es zeigt sich jedoch, daß diese nach kurzer Eelastungsdauer nachläßt. 5 Offenbar beruht diese nachteilige Erscheinung auf einem Polarisationseffekt, denn Versuche, bei denen die Zellen vor der Wechselstromprüfung mit Gleichstrom behandelt wurden, haben ergeben, daß das Übersetzungsverhältnis, d. h. der Quotient, aus dem zugeführten Wechselstrom und dem gewonnenen Gleichstrom abhängig \-on der Richtung, Stärke und Dauer der Vorbehandlung mit Gleichstrom ist, und zwar wurde durch die Vorbehandlung mit Gleichstrom im allgemeinen eine ungünstige Einwirkung auf das Übersetzungsverhältnis festgestellt.It is known that cells made of copper iodine have rectifying electrodes with various metal electrodes Effect. It turns out, however, that this subsides after a short period of exposure. 5 This disadvantageous phenomenon is apparently based on a polarization effect, because attempts in which the cells are treated with direct current before the alternating current test have shown that the gear ratio, i.e. H. the quotient from the supplied Alternating current and the direct current obtained depending on the direction, Strength and duration of the pretreatment with direct current is, and that was by the Pretreatment with direct current generally found an adverse effect on the gear ratio.
Erfindungsgemäß wird nun die schädliche Wirkung des Polarisationseffektes dadurch erheblich herabgemindert und sogar im wesentlichen gänzlich ausgeschaltet, daß dem Kupferjodür Oxydationsmittel, wie Persalze oder Superoxyde, zugefügt werden. Durch solche Zusätze zum Kupferjodür wurde das Übersetzungsverhältnis fast unabhängig von der Vorbehandlung mit Gleichstrom, und dementsprechend wurde eine wesentlich größere Lebensdauer der Zelle in der Verwendung als Gleichrichter erzielt. Kurven, die das Über-According to the invention, the harmful effect of the polarization effect is now thereby considerably diminished and even essentially completely eliminated that dem Copper iodine for oxidizing agents such as persalts or super oxides. By Such additions to the copper iodine became almost independent of the gear ratio the pretreatment with direct current, and accordingly a much larger one Lifetime of the cell achieved in use as a rectifier. Curves that

von 1,34, mit Zusatz von Oxydationsmitteln dagegen eine solche von nur 0,0016. Die mittlere Steilheit liegt also im letzteren Falle in ganz anderer Größenanordnung. Das Oxydationsmittel wirkt dabei offenbar als Depolarisator. 4-5of 1.34, with the addition of oxidizing agents, on the other hand, that of only 0.0016. the The mean slope in the latter case is therefore in a completely different order of magnitude.

Es ist bereits vorgeschlagen worden, die gleichrichtende Schicht für einen Trockengleichrichter in der Weise herzustellen, daß Blei mit Kupferjodür, dem Jod im Überschuß zugesetzt ist, in Berührung gebracht wird, zu dem Zweck, daß an der Berührungsstelle durch chemische Einwirkung des überschüssigen Jods auf das Blei Bleijodür gebildet wird. Der Zusatz von Jod ist hier vorgenommen lediglich mit dem Ziel, eine schlecht leitende Schicht in Form von Bleijodür zu erhalten. Daß das Jod etwa die Eigenschaft besitzt, bei einem Kupferjodürgleichrichter, ganz unabhängig davon, mit welcher Gegenplatte die Kupferjodürschicht in Kontakt steht, infolge seiner oxydierenden Wirkung den Betrieb des Gleichrichters zu verbessern, wurde dagegen nicht erkannt.The rectifying layer for a dry rectifier has already been proposed to be produced in such a way that lead is brought into contact with copper iodine to which excess iodine is added, for the purpose that at the point of contact by chemical action of the excess Iodine on the lead lead iodine is formed. The addition of iodine is made here only with the aim of obtaining a poorly conductive layer in the form of lead iodine. The fact that iodine has the property of a copper iodine rectifier, quite regardless of which counterplate the copper iodine layer is in contact with, as a result On the other hand, it was not recognized that its oxidizing effect could improve the operation of the rectifier.
Der vorliegenden Erfindung liegt nun die Erkenntnis zugrunde, daß nicht nur der Zusatz von Jod, sondern überhaupt der ZusatzThe present invention is based on the knowledge that not only the addition of iodine, but the addition in general
