WebElectrochemical hydrogen pumping based on low-temperature proton exchange membranes was originally developed in the 1960s [8,9]. Fundamentally, an electrochem-ical pump is designed to oxidize and reduce hydrogen at the anode and cathode, respectively in an electrolytic mode. As shown in Fig. 1, a hydrogen-containing stream … WebHydrogen compressor. A hydrogen compressor is a device that increases the pressure of hydrogen by reducing its volume resulting in compressed hydrogen or liquid hydrogen . Traditionally, applications for hydrogen compressors included Chlorine electrolyser and many chemical applications like the production of hydrogen peroxide (HPPO). The … Web2 pump rate: 2 e ~ H 2 Special membranes block hydrogen gas, but allow fast proton conductivity. Catalysed interfaces enable the indicated redox reaction equilibrium. An external power source drives the electric current and the internal hydrogen mass transport direction, controlling hydrogen gas flow. trinity old scholars
