What is it about?
Solid oxide fuel cell convert chemical energy of a fuel into electricity, and their working mechanism require oxygen ions from air to enter into a solid electrolyte to reach the fuel. Better ionic transport allows low operation temperature and longer lifetime. We studied how a material used to transport oxygen ions in fuel cells exchanges oxygen to explain why our production method improves the performances in otherwise industrial devices. To do so we used operando soft x-ray spectroscopy and Raman spectroscopy.

Why is it important?
We use physical vapor deposition to create thinner layers without using solvants or high processing temperature. This more sustainable production method allows use of less raw materials and aims at making the technology more accessible and widespread.
Perspectives
As a solid state physicist I am very interested in bringing together experimental tools such as synchrotron-based soft x-ray spectroscopy and energy materials and devices.
