Beschreibung
Zusammenfassung:	The invention relates to a catalytically active porous element and to a method of manufacturing same. The element is formed with at least 40% by mass cobalt and at least one further chemical element and/or at least one chemical compound which form a matrix into which particles of pure cobalt, of a cobalt alloy or of an intermetallic phase formed with cobalt are embedded. In this respect, the at least one chemical element and/or the at least one chemical compound have a lower sintering temperature and/or melting temperature than cobalt, the respective cobalt alloy or the intermetallic phase. Solely for this purpose or in addition thereto, cobalt can be partially soluble therein and/or can form a eutectic and/or a peritectic together with cobalt.
