Abstract: The energy transition targets amplify the need for economically viable hydrogen related technologies. Proton conducting ceramic cells (PCCs) are a novel and challenging technology that offers application windows at moderately increased temperature and further multitude of advantages compared to the conventional Solid Oxide Cells (SOCs). Despite this, the technological readiness level of PCCs trails behind that of SOCs due to several reasons related to the challenging nature of BaZr1-x(Ce,Y)xO3-δ (x=0.3-0.5, BZCY) based proton conducting ceramics, high temperature processing and relatively limited scalability. The present work focuses on the approaches related to optimization of the cell materials and components development to final PCCs. Following the technological chain from ceramic powder synthesis via wet chemical and solid state routes to the development of tape cast slurries, screen printing pastes or nano-suspensions, the decisive technological steps in the PCCs fabrication are outlined in the light of cell components microstructure, phase composition, their thermo-chemical stability and overall KPIs performance.
