Development of membranes for hydrogen fuel cells and electrolyzers for hydrogen production

In this thesis, we delve into the increasingly significant field of sustainable hydrogen production, a pivotal component for the future of clean energy. Our primary focus is on the utilization and detailed analysis of proton exchange membranes. These are essential for the selective ion transport, especially protons (H+), in hydrogen production. The initial section offers an in-depth overview of hydrogen's growing role as an energy carrier and elaborates on its primary production mechanisms. We then transition into the evolution of membranes for hydrogen transport. Here, we spotlight the outdated Nafion-based membranes and introduce the innovative intrinsically microporous polymers (PIM) membranes as a promising alternative. In the subsequent section, I share insights from my tenure at the Italian Institute of Technology in Turin. This includes the tools and analytical methods used for polymer synthesis. The next chapter provides a meticulous breakdown of the entire process, coupled with a critical evaluation of the results. The fourth and fifth chapters elucidate the pivotal steps in producing membranes using the newly developed polymer. In our conclusion, we encapsulate the research journey, emphasizing the outcomes and reflecting on my experiences within the research team. This thesis stands as a noteworthy addition to sustainable hydrogen production research. I believe it holds the potential to catalyze further advancements in this vital sector for our planet's energy future.
