Abstract
Electrochemical Hydrogen Compression presents solutions to realizing a hydrogen infrastructure and thus providing a sustainable energy network. This technology enables typical bottlenecks of purification and compression to be surpassed simultaneously, but functions only for hydrogen gas specifically. HyET has developed a membrane for electrochemical hydrogen compression showing superior proton conductivity in combination with minimal hydrogen back-diffusion characteristics, to be able to compress to pressures as high as 100 MPa with a competitive energy requirement.
