Development of advanced PEM water electrolysers

Concerning the production of electrolytic hydrogen, the goal of present R and D is to develop advanced hydrogen generator based on proton exchange membrane (PEM) water electrolysers. PEM-based water electrolysis offers a number of advantages, such as ecological safety, high gas purity (more than 99.99% for hydrogen), the possibility of producing compressed gases (up to 200 bar) for direct pressurized storage without additional power inputs, etc. PEM electrolysers are considered as rather attractive devices to accelerate the transition to the hydrogen economy and develop a hydrogen infrastructure network (for example for the development of re-filling stations for cars, using electric power stations at night hours and renewable energy sources). The work presented here result from a cooperation between Hydrogen Energy and Plasma Technology Institute (HEPTI) of Russian Research Center (RRC) 'Kurchatov Institute', Universite Paris - Sud XI and Compagnie d'Etudes des Technologies de l'Hydrogene. This project is supported by the Commission of the European Communities within the frame of the 6. Framework Programme (GenHyPEM, STREP no 019802). (authors)
