We are currently developing an electrochemical compressor and have already been able to demonstrate with a prototype that our concept of hydraulic compression can also be used for pneumatics, i.e. with gases (hydrogen and nitrogen in this case). The "pneumatic compression" was combined here with a mechanical screw connection and two electrochemical compressors were connected in series and compressed in 2 pressure stages atmospheric water pressure to 30 bar and then to 60 bar.
The prototype was tested on a small scale (active area 25cm²) and is currently being scaled up and made ready for production.
The work on the prototype has been recorded in a publication.
Please contact us if you are interested in our compressor or if you want to receive more information about it or about the development status.
