The proton conducting ceramics cell, operating at moderate temperatures (400-600 ° C), is ideal in respect of utilization of Hydrogen. By allowing hydrogenation or dehydrogenation, proton conducting cells offer incomparable benefit for defossilizing the chemical industry, for instance by allowing electrochemical production of chemicals such as ethylene, or ammonia.
We propose an alternative and innovative concept of metal supported cells using proton conducting ceramics as electrochemical energy conversion devices, including fuel cell and electrolysis applications. Replacing the thick porous ceramic substrate by inexpensive porous metal will increase the robustness of the cell, while reducing the needs for critical raw materials widely used in technical ceramics and costs.
Many challenges regarding materials selection remain open. The performance will be improved to reach the critical level for practical applications when reliable oxygen+steam electrode is developed. Another hurdle is to develop a processing route to manufacture pinhole-free coating of proton conducting electrolyte at mild condition (below 1000°C) compatible with the use of metallic substrate.
In support of current development efforts at the University of Oslo and SINTEF, in the frame of the Norwegian project AH2A, and at DLR, the DAICHI project aims at supporting international collaboration and exchanges. Both Kyushu and Tohoku universities will provide additional fundamental knowledges and expertise for the investigation and further development of the key materials. Allowing efficient and effective scientific exchange of knowledge between Europe and Japan, DAICHI will speed up the technological developments and foster emergence of international scientific excellence in the field.
The project is funded by the programm EIG Concert Japan.
Duration: April 2018 - March 2021
