An electrochemical compressor that selectively extracts hydrogen from several different gas mixtures is compact, silent and proven to outperform any mechanical hydrogen compressor whether it is being used for home refuelling systems, public refuelling stations or other large-scale industrial uses.

Source: HyET HydrogenHyET Hydrogen’s HCS 100 electrochemical compressor opens up new possibilities for the fuel cell electric vehicle (FCEV) market including small-scale residential hydrogen generation. The unit can handle several gas mixtures that contain various ratios of methane, carbon dioxide, carbon monoxide, nitrogen and hydrogen sulfide.

The integrated Membrane Electrode Assembly (MEA) provides a fine balance of proton conductivity, barrier characteristics and mechanical strength. The catalyzed membrane interfaces increase the redox potential of hydrogen allowing for efficient proton transport while blocking hydrogen gas molecules as well as permeation of any other gas present in the low-pressure gas mixture being supplied.

The flanged unit is scalable, has no moving parts and does not require a backup compressor. The system only requires an external power source to drive the redox potential and control proton mass transport.
