Nanobubbles have gained significant attention in diverse fields due to their distinctive characteristics, leading to the development of innovative applications catering to a wide range of requirements. Concurrently, proton exchange membrane water electrolysis (PEMWE) holds immense potential for sustainable energy conversion and storage. This thesis explores unknown territory by investigating the utilization of Moleaer air nanobubble water in PEMWE cells. The primary objective is to comprehend the potential benefits and challenges. This thesis provides an overview of the fundamentals, synthesis, and characterization of air nanobubble water used in PEMWE. Detailed documentation is presented regarding the fabrication of PEMWE cells and the setup of the electrochemical testbed. Through the implementation of various techniques, the impact of air nanobubble water on crucial performance parameters, including current density, impedance, and stability, is assessed, with traditional deionized water used as a benchmark. The careful analysis of the acquired results reveals the influence of air nanobubble water on the performance of PEMWE cells. This thesis proposes further research and optimization to comprehensively interpret the experimental outcomes and elucidate the underlying mechanisms pertaining to the application of air nanobubble water in PEMWE cells.
