Abstract

Die Erfindung betrifft einen Wasserstoffgenerator, aufweisend einen ersten Bereich mit einer Legierung und einen zweiten Bereich, welcher vom ersten Bereich getrennt ist und in welchem eine flüssige oder gasförmige Phase vorliegt, aus der durch Kontakt mit der Legierung Wasserstoff freisetzbar ist, wobei die flüssige oder gasförmige Phase zur Legierung bzw. die Legierung zur flüssigen oder gasförmigen Phase transportierbar ist. Um eine vollständige, aber langsame Freisetzung von Wasserstoff aus einer Legierung bei Kontakt mit der flüssigen oder gasförmigen Phase zu ermöglichen, ist erfindungsgemäß vorgesehen, dass die Legierung im Wesentlichen aus Alkalimetall und/oder Erdalkalimetall sowie einem oder mehreren Elementen der Hauptgruppen III, IV, V und/oder der Nebengruppen Ib, IIb des Periodensystems der Elemente und/oder Eisen und/oder Nickel besteht, wobei Lithium-Aluminium-Legierungen und binäre Legierungen von Alkalimetallen mit Silicon ausgenommen sind.
