The Efficiencies of Internal Reforming Molten Carbonate Fuel Cell Fueled by Natural Gas and Synthetic Natural Gas From Coal
Autor: Hee Chun Lim, Won-Shik Park, Hai-Kyung Seo
Publikováno v: Journal of Electrochemical Energy Conversion and Storage. 13
When synthetic natural gas (SNG) is produced from coal and used as a fuel in the internal reforming molten carbonate fuel cell (ir-MCFC), electric efficiency can be no greater than 31%. This is because there are several exothermic reactions in the pr
