“…The MCFC as the hydrogen, electric power, and heat trigeneration system [8] has been studied by many methods to propose the MCFC as the carbon capture system in fossil fired power plants [9,10], examine the effect of the materials [11] and thickness [12] of electrodes and reactant [13] on the stability of the MCFC, and model the performance characteristics of the MCFC [14,15]. When a MCFC is operated, there are the waste heat produced in the system [16] and the residual hydrogen from the anode of the fuel cell [17], the general method to deal with the heat from MCFC is to release it into the environment [18,19].…”

a b s t r a c tA novel model of the molten carbonate fuel cell (MCFC) and gas turbine (GT) hybrid system with direct internal reforming is established, where the fuel cell and the auxiliary burner are taken as the heat reservoirs of the GT. Expressions for the power output and efficiency of the hybrid system are derived by considering various irreversible losses resulting from the overpotentials in the MCFC, the heat leakage in the auxiliary burner, and the finite-rate heat transfer and compression, expansion, and regeneration processes in the GT. The effects of some key parameters including the molar fraction of the oxygen in the oxidant, the utilization factor of the hydrogen in the MCFC on the performance of the hybrid system are revealed. It is found that the efficiency of the hybrid system will be increased by adding the utilization factor of the hydrogen, and the maximum power output of the hybrid system will be achieved when the utilization factor of the hydrogen is equal to 0.78. Moreover, the flowing rates of the syngas and oxidant and the molar fraction of the oxygen in the oxidant are determined under the optimal efficiency or maximum power output of the hybrid system.

“…Within this context, fuel cells, especially MCFC (molten carbonate fuel cell) and SOFC (solid oxide fuel cell) have come into sight as competent alternatives to conventional power generation methods [5]. MCFC as a typical high-temperature fuel cell has attracted a great deal of attention due to its high efficiency, low emission of pollutants, and fuel flexibility based on its resistance to fuel impurities such as CO (carbon monoxide) [6]. Moreover, operation at elevated temperatures (600e700 C) entails sufficient fast kinetics, allowing MCFC to use relatively inexpensive nonnoble catalysts (Ni vs. Pt) [7].…”

“…The application of porous inorganic films for gas separation has received increasing attention due to their unique thermal, chemical, and mechanical stability (1)(2)(3)(4)(5). These films or membranes may consist of a single oxide such as silica (SiO 2 ), alumina (Al 2 O 3 ), titania (TiO 2 ), or zirconia (ZrO 2 ) or a combination thereof (composite membranes) in order to yield specific properties that improve gas separation performances.…”

Microporous silica membrane containing hydrotalcite (HT) was prepared successfully without losing the former's molecular sieving property. The microporous HT-silica membrane (200 nm in thickness) was formed on the surface of mesoporous γ-alumina layer (9 μm in thickness) and supported by macroporous α-alumina substrate (ca. 2 mm in thickness). The pore size of the microporous HT-silica membrane was 8.5Å, slightly larger than the pristine silica membrane (5Å). The composite membrane was found to enhance the permeability of gases and permselectivity of carbon dioxide from gas mixture comprising methane, hydrogen or nitrogen. Microporous HT-silica membrane with 15 vol.% HT displayed the highest permselectivities in the order of CO 2 /CH 4 > CO 2 /N 2 > CO 2 /H 2 and the permselectivities decreased with increasing HT content.
