Investigation of Quality Criteria in the Production of PEM Electrolyzer Stacks

Due to the increasing demand for green hydrogen, driven by global efforts to decarbonize various sectors, the industry is dedicated to scaling up the production of hydrogen electrolyzers. In response to this, current research projects aim to establish fully automated assembly plants for hydrogen electrolyzers. An essential step in this process is the focus on solutions for quality testing and error identification. In the following work, by synthesizing existing literature and insights from domain experts through interviews, potential errors and influences associated with electrolyzer stacks and their components are investigated. Furthermore, recommendations for effective quality testing are outlined. Through this research, the groundwork for decision-making and the development of robust quality assurance within the context of automated electrolyzer stack production is provided.
