Molten carbonate fuel cell



Wikipedia states:

Molten-carbonate fuel cells (MCFCs) are high-temperature fuel cells, that operate at temperatures of 600°C and above.

Molten carbonate fuel cells (MCFCs) are currently being developed for natural gas, biogas (produced as a result of anaerobic digestion or biomass gasification) , and coal-based power plants for electrical utility, industrial, and military applications.

MCFC diagram

MCFCs are high-temperature fuel cells that use an electrolyte composed of a molten carbonate salt mixture suspended in a porous, chemically inert ceramic matrix of beta-alumina solid electrolyte (BASE). Since they operate at extremely high temperatures of 650°C (roughly 1,200°F) and above, non-precious metals can be used as catalysts at the anode and cathode, reducing costs.


Mathematical model

Sundmacher et. al models the MCFC as as non-linear 2-dimentional partial differential equations using mass and energy flow balance equations.
