Molten-carbonate fuel cells - MCFC
Molten-carbonate fuel cells (MCFCs) can operate at very high temperatures of 600C and above. It is utilizes for natural gas, biomass, and coal plants. It uses molten carbonate salt as electrolyte suspended in porous beta alumina solid electrolyte.
MCFC can achieve 60% efficiency utilization and if heat is captured this efficiency can go up as high as 85%. MCFCs don't need external reformer. High temperatures makes fuel of MCFC into hydrogen within the fuel cell by the process called internal reforming.
