Preferential Oxidation (PROX) Catalyst For Carbon Monoxide
PROX = Preferential Oxidation
This catalyst is used to selectively oxidize carbon monoxide from reforming gas in PEFC.
In proton-exchange membrane fuel cells (PEFCs), a reforming gas that contains hydrogen (H2) is used. This reforming gas also contains a certain amount of carbon monoxide (CO). Because CO poison electrodes, and deteriorate battery performance, the concentration of CO in the reforming gas should be below 10 ppm. PROX catalyst is a catalyst to selectively oxidize CO in reforming gas to carbon dioxide (CO2).
- High activity even at a high space velocity owing to highly dispersed catalytic precious metal
- Activity is maintained at a wide range of temperatures from low to high
- Despite a low precious metal content, the catalysts maintain a high level of activity, which enables us to offer catalysts at low cost
