Effect of gas-phase transport in molten carbonate fuel cell

Electrode performance of a new La0.6Sr0.4Co0.2Fe0.8O3 coated cathode for molten carbonate fuel cells

“…As shown in this figure, the slopes of both of ln R high frequency vs ln pO 2 [31,32]. They were also observed that the exchange current density in La 1Àx Sr x CoO 3 electrode was independent of the O 2 partial pressure [30].…”

An analysis for a molten carbonate fuel cell of complex geometry using three-dimensional transport equations with electrochemical reactions

“…(2) as follows: k eff , x ¼ 0.128 W m À1 K À1 , k eff , y ¼ 0.305 W m À1 K À1 , and k eff , z ¼ 1.054 W m À1 K À1 . Before proceeding further with the calculation, the procedure is validated against measured data for the unit cell reported by Lee et al [25]. The cell shape is identical to that of the present case but the reaction area is much smaller, i.e., 10 cm  10 cm.…”

Oxidation of ash-free coal in a direct carbon fuel cell

“…The carbon was made from oak carbonized at 1200 C. The H 2 fuel shows a very mild slope, which indicates H 2 oxidation has very low reaction resistance. This finding indicates that the reaction rate of H 2 fuel is very high, and its mass transfer is sufficiently fast because H 2 oxidation is under the masstransfer control region [21]. Thus, the H 2 fuel was used as a reference for the oxidation behaviour.…”

“…The gas oxidation in the anode of the MCFC was found to be mostly a gas phase mass-transfer control process [21]. The steeper slope of carbon fuel indicates that the oxidation of CO has a much larger resistance than H 2 fuel.…”
