Two sets of solid oxide fuel cell (SOFC) electrode assemblies from different manufacturers were run under different operating conditions with different sulfur exposure, and then subjected to X-ray absorption spectroscopy (XAS) at the sulfur K (1s) edge. Within the detection limits of the spectrometer, pristine fuel electrodes (anodes) show no traces of sulfur. The anodes operated with sulfur-containing...
Least square analysis of the X-ray absorption near edge structure (XANES) region of sulfur K edge X-ray absorption fine structure (XAFS) spectra can provide a quantitative analysis of both the organic and inorganic functional forms of sulfur in coal. In the current article, this method is applied to speciation of the sulfur forms in a number of desulfurized coals. The samples investigated include...
