Descrizione: According to the Fit for 55 package, REPowerEU plan, and Renewable Energy Directive III, sustainable hydrogen production constitutes a strategic priority for decarbonizing hard-to-abate sectors. As an energy carrier, hydrogen must be produced. While conventional water electrolysis technologies (Alkaline, Proton Exchange Membrane, and Anion Exchange Membrane Electrolyzers) are mature, they present significant technical and economic barriers to large-scale deployment. Proton-Conducting Ceramic Electrolyzers (PCCELs) offer innovative potential: operating at intermediate temperatures (400–600°C) enables non-precious materials for cost savings. Separate hydrogen production eliminates downstream separators and compressors, reducing plant size and installation costs. However, operation at such temperatures still accelerates material degradation, limiting efficiency and productivity. Research thus focuses on materials and single-cells, lacking integrated stack/system assessments, economic feasibility studies, and env
