Novel nano thin film oxygen electrodes for solid oxide cells

Objective

The EU goal of cutting greenhouse gas to zero net emissions by 2050 will put particular pressure on energy conversion and storage systems. Reversible Solid Oxide Cells (rSOCs) capable of efficiently operating in two modes: as solid oxide fuel cell and as solid oxide electrolyser cell, are of particular interest. To operate the cells with high efficiency and long duration, scrutiny of potential oxygen electrode materials and development of novel materials for intermediate temperature (IT)-SOCs is essential. However, a methodology to screen the oxygen surface exchange and bulk diffusion kinetics with a ubiquitous, easily accessible and reliable technique is still in high demand. The fellowship aims to address these urgent demands towards a green economy. Two chemical vapour deposition methods, metalorganic chemical vapour deposition (MOCVD) and atomic layer deposition (ALD), will be wisely combined for obtaining thin film preparation with improved nano-morphology. Pr-doped La2NiO4±δ thin films (LPNO) with surface modification will be prepared, to improve the electrochemical properties while maintaining good ionic conductivity. The development of the unique in situ isotopic exchange Raman spectroscopy (IERS) technique and apparatus, will be the second core task of this project. This novel Raman technique will be used as an alternative and complementary technique to the conventional approach, proving more efficient, accessible and nondestructive in situ measurements. For the candidate, as part of her continuing interest in electroceramics, the project will link perfectly with her previous experience and will provide her with the opportunity of applying her in depth knowledge to develop novel new skills in the area of solid state ionics, especially for nanoscale thin films. On the long term she will be able to extend and broaden her existing academic and industrial network and advance her career prospects.
