Microstructured reactors for diesel steam reforming, water-gas shift and preferential oxidation in the kiloWatt power range

The second clean-up stage, namely the preferential oxidation reactor, was designed as a co-current heat-exchanger. Water evaporation was chosen as the cooling source. The CO could be reduced under most operating conditions to levels below 100 ppm, which is sufficient to operate a CO-tolerant low temperature PEM fuel cell with the purified reformate.
