Understanding the Impact of Sulfur Poisoning on the Methane-Reforming Activity of a Solid Oxide Fuel Cell Anode

Abstract: Natural gas is one of the most attractive fuels for solid oxide fuel cells (SOFCs) because of the existing fuel distribution infrastructure. Unfortunately, natural gas routinely contains small concentrations of sulfur-containing compounds, which may result in degradation in performance of fuel cells due to sulfur poisoning of Ni-based anodes. To date, the deactivation mechanism of anodes by sulfur remains poorly understood, making it extremely challenging to mitigate the problem. Here, we report our findings i… Show more

“…The non-vacuum nature of Raman spectroscopy makes it very suitable for solid oxide fuel cell (SOFC)/SOEC material characterization. [40][41][42][43][44][45] We prepared a model cell and performed the in situ Raman spectroscopy analysis to investigate the impact of the electric bias on the surface reactions. 40,41,45 The sample preparation procedure and test configuration are shown in Fig.…”

“…Owing to the very low concentration of sulfur in the fuel gas, the low detection limit of traditional characterization methods makes it impossible to obtain accurate surface information. Liu et al employed in situ SERS to study the effect of sulfur poisoning on the catalytic activity of Ni YSZ anode during SMR [80]. According to the experimental observation and calculation results (Figure 12a,b), the SMR reaction was as follows:…”

“…8 As an eco-friendly power source, a SOFC represents one of the most competitive options to convert chemical fuels into electricity in a clean and sustainable manner. 9–14 Generally, power generation by the device hinges critically on the oxygen reduction reaction (ORR) rate; hence, a grand overarching goal for researchers has been the development of a high-performance cathode. 15–17 For this purpose, composite electrodes have been routinely employed in the field of SOFCs, which are, in fact, a form of multi-phase catalyst.…”
