“…Of primary concern to the fuel cell system are halocarbons, as they convert to acid gas that can corrode catalytic surfaces [22][23][24]. For Molten Carbonate Fuel Cells (MCFC's), degradation due to halogens is also a long term effect; halogens react with the electrolyte, thereby affecting the performance of the MCFC over time [23,25].…”

“…Within an MCFC system, the temperature is typically at about 600°C. This is high enough to allow for internal reforming, the production of hydrogen from different types of fuels such as natural gas, waste gas or gas from bio mass fermentation [4]. Also, no expensive catalysts are required due to the high temperatures; nickel and nickel oxide are sufficiently active to be used as reforming catalyst and electrode catalysts.…”

A model of a molten carbonate fuel cell (MCFC) stack including internal steam reforming is presented. It comprises a symmetric section of the stack, consisting of one half indirect internal reforming unit (IIR) and four fuel cells. The model describes the gas phase compositions, the gas and solid temperatures and the current density distribution within the highly integrated system. The model assumptions, the differential equations and boundary conditions as well as the coupling equations used in the model are shown. The strategy to solve the system of partial differential equations is outlined. The simulation results show that the fuel cells within the stack operate at different temperatures. This is expected to have an impact on the voltages as well as the degradation rates within the individual fuel cells. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA,Weinheim [accessed September 2nd, 2010

“…6) If the use of biogas made from waste is possible, it could save fossil fuels. There are many different types of biogas, 11,12) including anaerobic digester gas (ADG), landfill gas (LFG), syngas from an entrained bed steam gasifier (EBG), and syngas from a dual interconnected fluidized bed steam gasifier (DBG).…”

“…Among the several poisons studied, H 2 S is one of the most harmful to MCFC stacks. 6,9,12) The H 2 S concentration in biogas can vary from 0.1% to 2% in feedstock to higher than 3% from manure and protein-rich organic wastes.…”

“…(It is known that MCFC can be accepted below 5 ppm of H 2 S without cell damage 6) ). Thus, the design of a biogas pretreatment system for use in a MCFC focuses on the removal of H 2 S. Other contaminant materials in biogas can be removed through treatment processes such as cooling, adsorption or absorption with inorganic and organic solvents.…”

Molten carbonate fuel cell (MCFC) power plants are one of most attractive electricity generation systems for the use of biogas to generate high-efficiency ultra-clean power. However, MCFCs are considerably more expensive than comparable conventional electricity generation systems. The commercialization of MCFCs has been delayed more than expected. After being effective in the Kyoto protocol and considerably increasing the fossil price, the attention focused on CO 2 regression and renewable energy sources has increased dramatically. In particular, the commercialization and application of MCFC systems fed with biogas have been revived because of the characteristics of CO 2 collection and fuel variety of MCFCs. Better economic results of MCFC systems fed with biogas are expected because biogas is a relatively inexpensive fuel compared to liquefied natural gas (LNG). However, the pretreatment cost is added when using anaerobic digester gas (ADG), one of the biogases, as a fuel of MCFC systems because it contains high H 2 S and other contaminants, which are harmful sources to the MCFC stack in ADG. Thus, an accurate economic analysis and comparison between MCFCs fed with biogas and LNG are very necessary before the installation of an MCFC system fed with biogas in a plant. In this paper, the economic analysis of an MCFC fed with ADG was carried out for various conditions of electricity and fuel price and compared with the case of an MCFC fed with LNG.
