Katalysatormatta för rekombinering av väte och syre, speciellt vid användning av elackumulatorer uppstSende gaser, vilken matta framställts genom att impregnera ett bärarämne av polytetrafluoreten och aktivkol med ett katalytiskt aktivt ämne, och genom valsning, kännetecknad därav, att av en polytetrafluoreten-aktivkol-blandning valsats en första matta, att mattan impregnerats med en vattenhaltig lösning av ett sait baserat pä en katalytiskt aktiv metall, att mattan härefter gjorts vattenfast och sintrats, och att i närä mekanisk kontakt med denna matta bringats en andra aktivkolmatta fri fr&n katalytiskt aktivt ämne.
2. Katalysator enligt patentkravet 1, kännetecknad därav, att blandningsförhällandet polytetrafluoretenraktivkol är mellan 40:60 viktprocent och 10:90 viktprocent, lämpligast 25:75 viktprocent.
3. Katalysator enligt patentkraven 1 och 2, kännetecknad därav, att den första mattan innehäller 0,1-5 viktprocent, lämpligast 0,3-1 viktprocent palladium.
4. Katalysator enligt patentkravet 3, kännetecknad därav, att den andra, katalytiskt icke aktiva kolmattan impregnerats med kopparoxid.
5. Förfarande för framställning av en katalysator enligt nägot av patentkraven 1-4, kännetecknat därav, att polytetrafluoreten-aktivkol-blandningen valsas tili en matta, att mattan mättas med palladiumkloridlösning och efter mellan-torkning väts med en vattenhaltig polytetrafluoreten-dispersion, att mattan efter förnyad mellantorkning underkastas sintring i indifferent eller reducerande ugnsluft, att en andra matta framställes utan PdCl2-mättning och att bägge mattorna bringas tili närä mekanisk kontakt.
