Optimization of high Performance nano-architectured electrode/electrolyte bilayer for Solid Oxide Cells (OPEN SOC project)
Goals
- Develop novel electrode/electrolyte architectures with improved performance, i.e low Area Specific Resistance (ASR)
- Understand and quantify the combined effects on ASR of architecture, enhance ionic conductivity and enhance ORR kinetics
Model development and FEM simulations:
- Simulations on COMSOL Multiphysics
Deposition, characterization and tuning of the electrolyte and electrode materials:
- Dense polycrystalline, strained epitaxial and dense-porous hierarchical films
- X-ray diffraction (Theta-2theta, GIXRD, Reflectometry), atomic force microscopy and electron microscopy (FEG-SEM, TEM)
Functional electrical and electrochemical properties of the µ-SOCs:
- Conductivity measurements vs temperature (Van der Pauw),
- Electrical conductivity relaxation (ECR),
- Electrochemical impedance spectroscopy (EIS)
- Degradation measurements as a function of time (electrodes films or electrode/electrolyte half-cells)
