Glass ceramics with proton conducting crystalline phases — •Laura Weisshoff1,2, Martin Letz1,2, Martin Jourdan1, and Martun Hovhannisyan21Johannes Gutenberg Universität Mainz — 2Schott AG Mainz

Proton conducting crystal phases such as the perovskite type have their application in proton conducting fuel cells (PCFC), sensors and hydrogen separation. A reduction of the operating temperature due to highly efficient inorganic proton conducting materials is an important development target. For this, a proton-conducting electrolyte is a key component and an optimized material is required. Standard ceramic solutions show high sintering temperature and pores. A non-gas tight material can lead to a catastrophic failure of the PCFC. Therefore, we develop pore free glass ceramics with lower sintering temperature. The present talk reports the progress of glass ceramics with proton conducting crystalline phases.
