Governing Principles in Hydration of Mixed Conducting Oxides

The Project aims to establish the structural and chemical properties required for protonic mixed ionic-electronic conducting ceramics (P-MIECs)

About the Project

GoPHy MiCO addresses one of the main challenges in the development of new efficient energy systems based on Proton Ceramic Fuel Cells and Electrolysers, namely the identification of ceramics with mixed protonic and electronic conductivity. These are essential for the oxygen/steam electrodes, but only few and mediocre ones are identified. By systematically studying a set of double perovskites with different cations on distinguishable A-sites, and by systematic substitutions of these and also the B-site cation, trends in structures, oxidation, and hydration behaviour and conductivity will be established. The project outcome will potentially bring significant contributions to the ongoing implementation of hydrogen energy systems. Methodology to be employed comprises Neutron Powder Diffraction, electrochemical methods impedance spectroscopy, thermogravimetry, and ab initio atomistic modeling.

Financing

GoPHy MiCO is a M-era.Net Project, financed by the National Research Cousil of where the partners are from.
