| description | Die Erfindung betrifft multimetallische Legierungskatalysatoren zur Anwendung als Elektrodenkatalysatoren in Brennstoffzellen. Auf der Basis von carbidisierten Platin-Aluminium-Legierungskatalysatoren werden durch Zulegieren von Elementen der Gruppen VIB, VIIB, VIII und IB des Periodensystems Katalysatoren mit hoher Aktivität und Stabilität erhalten.
Pt-Al alloy catalyst on a conducting carbon carrier is claimed, in which the atomic ratio of Pt to Al is 80-60: 20-40 and the alloy particles are present on the carbon carrier in carbided form with the structure of the Pt-Al carbide (Pt3AlC0.5). Prodn. of the catalyst is also claimed. |
