Abstract

Here we analyze the effects of alkali carbonate (Na2CO3 and K2CO3) in a low-temperature ceramic fuel cell. The electrolyte consists of a composite of samarium doped cerium (Ce0.8Sm0.2O1.9) and carbonate. The alkali ions and
CO2 mixed with air as oxidant improved the power density and the open circuit voltage (OCV) of the fuel cell. The best results achieved showed a power density of 500 mW/cm2 and an OCV of 1.2 V at 500 oC. The highest OCV observed was 1.4 V. The fuel cell exhibits both molten carbonate and low-temperature solid oxide fuel cell
