Web10 de abr. de 2024 · Furthermore, the CSSFC exhibited ultrahigh ionic conductivity of 0.17 S⋅cm−1 at 550°C, leading to an unprecedented high open-circuit voltage (OCV) and a very high peak power density (PPD) as well as excellent coking resistance with dry methane fuel at 550°C. —Su et al. (A) Schematic of conventional SOFC, porous SOFC, and the CSSFC. WebThese fuel cells work well when provided with pure oxygen at the cathode but when the source of oxygen is air, residual levels of carbon dioxide can react with the electrolyte, forming carbonates which poison it. The cells are traditionally expensive compared to other types but their high efficiency makes them attractive for certain applications.
