Soft X-ray Imaging and Spectromicroscopy: New Insights in Chemical State and Morphology of the Key Components in Operating Fuel-Cells.

Monitoring of the redox reactions in simplified versions of PEFC and SOFC by the implementation of synchrotron-based soft X-ray microscopy methods, allows to explore the evolving structure and chemical composition of some key fuel cell components.
B. Bozzini et al., Chem. Eur. J. 2012, 18, 10196 – 10210.

This paper reviews the recent new insights on material stability issues of proton-exchange fuel-cells (PEFC) and solid-oxide fuel cells (SOFC) by monitoring of the redox reactions resulting in: 1) undesired deposits at interconnects and electrodes (PEFC); 2) material interactions at the electrode–electrolyte interface (PEFC); 3) release of corrosion products to the electrolyte phase (PEFC), and 4) mass-transport processes and structural changes occurring at the high operation temperatures of SOFC and promoted by the polarization.
These results demonstrate the great potencial of the soft X-ray microscopy methods

to investigate and identify morphological and chemical effects under the peculiar material-coupling conditions and environments developing in fuel cells operated at room- and high temperatures.
