A carbon monoxide PROX reactor for PEM fuel cell automotive application

摘要

Loughborough University have designed, constructed and evaluated a compact CO preferential oxidation (PROX) reactor for PEM fuel cell applications. The reactor design is based upon the catalyst coating of high surface area heat transfer technology. Catalyst screening studies have revealed a mixed transition metal oxide promoted platinum-ruthenium formulation to be suitable for the particular reactor application i.e. acceptable CO oxidation activity and selectivity within a temper- ature range of 130-200 deg.
