Hydrogen provided by electrolysis LT-PEMEC track

A Danish micro-electrolyser that is capable of efficiently splitting water into ultrapure hydrogen and oxygen has successfully been developed and tested within the present project. The electrolyser is based on the PEM technology that the IRD has developed for fuel cells and recently optimised for electrolysis. The electrolyser has a capacity of producing 1 Nm3 of H2 per hour, directly pressurized to 50 bar without a compressor. A drying system capable of reducing the dew point in a pressurised stage to less than -70ºC was also developed to comply with the dew point requirements for the use in a hydrogen filling station. The electrolysis system is CE certified. A number of prolonged cell test has been performed, the results show a huge potential for long lifetime i.e. one cell has successfully been tested for more than 3-years (30,000 hours), the test is still on-going.
