Last summer, from 18 to 22 August 2024, Budapest hosted the 14th International Conference on Ceramic Materials and Components for Energy and Environmental Systems (CMCEE14).
Wolff-Ragnar Kiebach – Head of Section Applied Ceramics and Processing at the Department of Energy Conversion and Storage of the Technical University of Denmark – presented the work entitled “Upscaling of proton conducting ceramic cells“.
Abstract:
Ceramics based on proton-conducting oxides are promising for a variety of applications, including fuel cells, electrolysis, hydrogen pumping, or chemical synthesis, but up-scaling of cells and stack remains a challenge. In this presentation, we will give an overview of ongoing activities at the Technical Uni[1]versity of Denmark (DTU Energy) to address this challenge. The latest results on upscaling planar proton-conducting ceramic cells (PCCs) based on Ba(Ce, Zr)O3 will be presented. Symmetrical and asymmetrical cells with an area of 140 cm2 can be produced, and the geometry and composition of the electrolyte and electrodes can varied/optimized for different applications. Also, the development of auxiliary components like interconnects and glass ceramic seal[1]ants needed to build stacks will be discussed. Furthermore, potential stacks design, which can circumvent challenges arising from the thermal expansion mismatches of the different materials used in PCC stacks, will be highlighted.
