Abstract
The design and construction of a sample holder for in operando X-ray absorption spectroscopy on solid oxide electrodes, like for instance the lanthanum strontium manganite electrodes, is explained. The sample holder is mounted in a test-cell, which is also described together with some preliminary test-results from temperature measurements and electrochemical characterisation performed on a "dummy" sample in the test cell. The test-cell is a modified version of a test-cell previously designed in our laboratory, and will in the future be used for X-ray absorption experiments on solid oxide electrodes.
Highlights
The perovskite La1-xSrxMnO3±δ (LSM) has found application as electrode material in solid oxide electrochemical cells, like the solid oxide fuel cells (SOFCs), solid oxide electrolysis cells (SOECs) and cells for electrochemical gas purification
