Acta 4020 Cathode Catalyst
Description
A noble metal free carbon based cathode catalyst for use in alkaline membrane fuel cells.
Composition
Standard composition: Approx. 3.5 wt. % transition metal on carbon support
Standard form: Fine powder
Physical properties
BET surface area: 690 m2 g-1
Pore volume: 1.6 cm3 g-1
Catalyst activity: A typical RDE cyclic voltammogram for the 4020 catalyst is shown here,
demonstrating performance as an oxygen reduction catalyst (fuel cell cathode).
