Sumario:"The increase in the proportion of renewable energy in the energy matrix and associated unpredictable electricity surpluses, the need for efficient forms of energy storage raises. Due to high energy density and transportability, hydrogen plays an important role as energy storage. After the production of hydrogen by electrolysis a significant percentage of the stored energy is used for the compression of the hydrogen gas. Higher efficiencies are reached by high pressure electrolysis, because subsequently compression of the hydrogen gas is not necessary. In the course of a cooperation between the Institute of Nuclear and Energy Technologies (IKET) and the Instituto Tecnológico de Buenos Aires (ITBA), a high pressure elec-trolyser Experiment has been developed at ITBA. The particularity about this device besides the high working pressure, are glass windows in the taps in order to be able to analyse the behaviour of the gas bubbles. Experiments for the investigation of the bubble behaviour have been performed at IKET. This master thesis describes the development of the project, from the design and construction of the electrolyser at ITBA, to the execution of first series of experiments at IKET. First conclusions about the bubble behaviour are presented".
