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 Here, we spotlight the outdated Nafion-based membranes and introduce the innovative intrinsically microporous polymers (PIM) membranes as a promising alternative.
