   B. NaBH-LösungenBeispiel 3 : Für die Versorgung der Kathode einer Brennstoffzelle, die einen zwar gleichmässigen, jedoch mengenmässig geringen Bedarf an Wasserstoff hat, wurde in das Druckgefäss eine Schüttung aus Nickelsinterkörpern eingebracht, die nach Massgabe des Wasserstoffverbrauches (Druck kontrolliert) kontinuierlich mit Boranatlösung versetzt wurden. 



   Hiebei vergingen sowohl bis zur ersten Gasentwicklung nach der Zugabe der Boranatlösung als auch bis zum Aufhören der Gasentwicklung nach Abstellen der Boranatzufuhr etwa   2-3 min.

   B. NaBH solutions Example 3: For the supply of the cathode of a fuel cell, which has a steady, but quantitatively low demand for hydrogen, a bed of sintered nickel bodies was placed in the pressure vessel, which is continuously supplied with boranate solution according to the hydrogen consumption (pressure controlled) were moved.



   In this case, about 2-3 minutes passed both until the first gas evolution after the addition of the boranate solution and until the gas evolution ceased after the boranate supply was switched off.

PATENTANSPRUCH : Verfahren zur Herstellung von Wasserstoff durch Zersetzen einer wässerigen Alkalimetallboranatlösung mittels metallischer Hydrierungs- und Dehydrierungs-Katalysatoren, wie Nickel, Palladium oder Platin, dadurch gekennzeichnet, dass man eine alkalische, wässerige Alkalimetallboranatlösung bei etwa normaler Temperatur durch eine Schüttung, einen Sinterkörper od. dgl. aus einem metallischen Hydrierungs-und Dehydrierungs-Katalysator hindurchdrückt. PATENT CLAIM: Process for the production of hydrogen by decomposing an aqueous alkali metal boranate solution by means of metallic hydrogenation and dehydrogenation catalysts, such as nickel, palladium or platinum, characterized in that an alkaline, aqueous alkali metal boranate solution at approximately normal temperature by a bed, a sintered body or the like. pushes through from a metallic hydrogenation and dehydrogenation catalyst.
