网页Technical design and market research of compressor systems and heat exchangers of a hydrogen fuel cell to increase the overall efficiency of the hydrogen production plant. Work packages: - Preliminary research - Design based on three different dimensioning scenarios - Market analysis of existing systems - Determining system specifications and ...
网页All experiments were performed inside the test chamber of the hydrogen test site HYKA at KIT (Karlsruhe Institute for Technology). With the dimensions 8 x 5.5 x 3.4 m this chamber is much larger than the jet region itself and therefore provides a suitable environment for the experiments on cryogenic free jets.
