Experimental Investigation of CO₂ Separation from Lignite Flue Gases by 100 cm² Single Molten Carbonate Fuel Cell

Abstract:

The paper presents an experimental investigation of using a Molten Carbonate Fuel Cell (MCFC) for reducing CO₂ emission from the flue gas of a lignite boiler. The MCFC is placed in the flue gas stream and separates CO₂ from the cathode side to the anode side. As a result, a mixture of CO₂ and H₂O is obtained; from which pure CO₂ can be obtained by cryogenic condensation of water and carbon dioxide. The main advantages of this solution are: additional electricity generated, reduced CO₂ emissions and higher system efficiency. The results obtained show that the use of an MCFC could reduce CO₂ emissions by 90% with over 30% efficiency in additional power generation.
