Protonic ceramic electrochemical cells in a metal supported architecture: challenges, status and prospects

Kurzfassung

Protonic ceramic cells (PCCs) offer variety of potential applications for electrochemical energy conversion, however a lot of challenges remain in the development of PCCs for industrial scale manufacturing processes. As it was successfully demonstrated for the solid oxide cells, metal supported architecture is a good alternative for PCCs with many attractive advantages in terms of stabilities in operation and reduction of raw critical materials. In this review, proposed architectures, component materials and processing options are summarized. The challenges and prospects are discussed.
