One of the biggest challenges today is to produce large amounts of energy in a sustainable way, to limit global warming caused largely by primary energy resources consumption such as fossil fuels. In recent years, much focus has been placed on hydrogen: it is an energy carrier that does not exist in nature in elemental form, consequently it must be extracted from other molecules (example: methane, water, hydrocarbons). In this thesis study, carried out at the Enapter company, a pre-design approach for an Anion exchange membrane (AEM) hydrogen production system is carried out. The different components of the electrolyzer are analysed, including both the structural and mechanical part.
