Abstract: The global effort for reaching highly efficient CO2-neutral energy supply requires innovative technological solutions based on high performance materials. Ceramic proton conductors (PC) with tailored properties gain increasing scientific and industrial interest due to their multifaceted applications at decreased temperatures. By means of proton conducting ceramic devices, energy can be either i) generated or co-generated together with valuable chemicals (fuel cells) or ii) stored into fuel (electrolyzers) or other energy carriers; iii) CO2 can be utilized in reactions with protons under certain oxygen withdrawal rates to formation of chemical products (CO2/H2O co-electrolyzers and catalytic membrane reactors); iv) various chemical processes can be intensified through equilibria shifts and carried out at beneficial operation conditions resulting in higher overall energy efficiency, products selectivity and yields. Aiming at realizing the lab-to-market technology readiness levels, large area ceramic cells are required at high cost efficiency besides the material high performance and durability. The present talk will give an overview of the development activities for realization of large scale planar cell design based on proton conducting ceramic and composite materials. Some similarities and / or differences to oxygen-ion conductors will be highlighted too.
