Electrochemical study of a planar solid oxide fuel cell: Role of support structures

An Isothermal Study of the Electrochemical Performance of Intermediate Temperature Solid Oxide Fuel Cells

“…The thick electrolyte layer usually results in high ohmic resistance. Thus, more effort is focussed on high temperature operation for electrolyte-supported SOFCs in a bid to reduce the ohmic resistance [39].…”

Comparison of humidified hydrogen and partly pre-reformed natural gas as fuel for solid oxide fuel cells applying computational fluid dynamics

“…where F is the Faraday's constant, k e´´ the pre-exponential factor (which is 6.5410 11  -1 m -2 for the anode and 2.3510 11  -1 m -2 for the cathode [25]), i 0 the exchange current density, R the ideal gas constant, AV e the electrochemical active area-to-volume ratio and E a,e the activation energy (137 kJ/mol for the cathode and 140 kJ/mol for the anode [16]). The potential difference between the anode and the cathode current collectors corresponds to the total cell operating voltage.…”

Three dimensional modeling of an solid oxide fuel cell coupling charge transfer phenomena with transport processes and heat generation

“…An activation energy (E a,e ) of 137 kJ/mol for the cathode and 140 kJ/mol for the anode are used by Patcharavorachot et al [20] and Aguiar et al [22] The heat generation by the electrochemical reactions and due to the losses through the activation, the ohmic and the concentration polarizations is given by [25]: (12) Here, i is the current density,  is the ion/electron conductivity, Q h is the heat generation/consumption and S r is the entropy change of the electrochemical reactions, calculated from the data in [37] for the anode and the cathode TPBs, respectively.…”
