CO Clean-up for Fuel Cells
- 5 kW Water Gas Shift Reactor
Where low temperature PEM fuel cells (Proton Exchange Membrane Fuel Cells) are the consumers of the reformate, the carbon monoxide (CO) content has to be minimized, sometimes to concentrations as low as 10 ppm. The situation is different when high temperature fuel cells, such as solid oxide fuel cells (SOFC Fuel Cells) are applied because they are capable of converting carbon monoxide. IMM can provide reactors for all necessary CO clean-up stages.
5 kW Water Gas Shift Reactor
As a first gas clean-up stage, the produced reformate can be sent to a water gas shift reactor where the CO concentration can be reduced to 1 vol% (1% = 10,000 ppm). The reactor plate stack is 214 mm long, 139 mm wide and 70mm high. The weight is 7.6 kg.
Reactors for Selective Oxidation or Preferential Oxidation
When it is necessary to reduce the carbon monoxide (CO) amount to 10 ppm or even lower then a preferential oxidation reactor (PROx) is necessary.
Compact Welded CO Selective Oxidation Reactor Heat Exchanger
- for smaller systems < 1 kW
- temperatures up to 200°C
- overall dimensions of 17 x 64 x 55 mm3
5 kWel Preferential Oxidation Reactor
This reactor is a co-current heat-exchanger where the reformate flow is cooled by water. The reactor plate stack is 234 x 83 x 93 mm and carries 7,760 channels. The weight of the reactor is 8.7 kg.
