“…It is shown that the cathode CO 2 gas removal rate of 105 cc/min at approximately 175 mA/cm 2 can be achieved. Figure 4 shows the CO 2 removal rate vs the current density achieved during the test [4]. The figure shows how the experimental values coincide perfectly with the theoretical values.…”

“…These results are encouraging taking into account the fact that the system involving fuel cell technology is an active system as compared to other systems which need a lot of energy to operate [1]. A recent study by K. Sugiura et al [4] elucidates the CO 2 removal characteristics of MCFC by performing experiments on a single cell MCFC with an electrode of area 81 cm 2 . It is shown that the cathode CO 2 gas removal rate of 105 cc/min at approximately 175 mA/cm 2 can be achieved.…”

“…Moreover, it can be seen that low concentration of CO 2 in the exhaust streams pose a challenge to the optimal performance of the MCFCs and this is also an active topic of research to enable the Molten Carbonate fuel cells to work efficiently at sub-optimal concentrations of CO 2 at fuel cell cathode as discussed in the studies by L. Caprile et al [3] and A. Amorelli et al [2]. In some studies the methods are also discussed to increase the performance of the fuel cells at lower CO 2 concentrations such as increasing the partial pressure of CO 2 as in the study by K. Sugiura et al [4].…”

Carbon dioxide is considered as one of the major contenders when the question of greenhouse effect arises. So for any industry or power plant it is of utmost importance to follow certain increasingly stringent environment protection rules and laws. So it is significant to keep eye on any possible methods to reduce carbon dioxide emissions in an efficient way. This paper reviews the available literature so as to try to provide an insight of the possibility of using Molten Carbonate Fuel Cells (MCFCs) as the carbon capturing and segregating devices and the various factors that affect the performance of MCFCs during the process of CO 2 capture.

“…The reformation process can occur directly within the anode gas channels and/or in separate in-stack plate reformers, as is the case for the current MCFC system. Use of a MCFC as a carbon dioxide concentrator was investigated experimentally by Sugiura et al [13], where it is showed that the experimental values for the CO 2 removal rate from cathode to anode performed in a MCFC almost matched theoretical calculations. One key conclusion from this work is that the ratio between the partial pressures of oxygen and carbon dioxide directly affects the performance.…”

h i g h l i g h t sSeparation of CO 2 in a biogas plant that co-produces electricity, hydrogen, and heat. The ability of MCFC is to concentrate CO 2 in the anode exhaust stream. Three cathode inlet configurations are considered. Results illustrate a high compatibility between hydrogen co-production and CO 2 recovery. A series configuration of MCFC technology coupled with an ICE achieves outstanding carbon recovery (exceeding 90%). a r t i c l e i n f o b s t r a c tThe possibility of separating and recovering CO 2 in a biogas plant that co-produces electricity, hydrogen, and heat is investigated. Exploiting the ability of a molten carbonate fuel cell (MCFC) to concentrate CO 2 in the anode exhaust stream reduces the energy consumption and complexity of CO 2 separation techniques that would otherwise be required to remove dilute CO 2 from combustion exhaust streams. Three potential CO 2 concentrating configurations are numerically simulated to evaluate potential CO 2 recovery rates: 1) anode oxidation and partial CO 2 recirculation, 2) integration with exhaust from an internal combustion engine, and 3) series connection of molten carbonate cathodes initially fed with internal combustion engine (ICE) exhaust. Physical models have been calibrated with data acquired from an operating MCFC tri-generating plant. Results illustrate a high compatibility between hydrogen coproduction and CO 2 recovery with series connection of molten carbonate systems offering the best results for efficient CO 2 recovery. In this case the carbon capture ratio (CCR) exceeds 73% for two systems in series and 90% for 3 MCFC in series. This remarkably high carbon recovery is possible with 1.4 MWe delivered by the ICE system and 0.9 MWe and about 350 kg day À1 of H 2 delivered by the three MCFC.
