Theoretical performance analysis of ethanol-fuelled solid oxide fuel cells with different electrolytes

The effect of electrolyte type on performance of solid oxide fuel cells running on hydrocarbon fuels

“…In addition, the current density of O-SOFC increases considerably as the reaction rate of CO electrochemical oxidation is increased (from J ). This result is contrary to our common understanding that H-SOFC always perform better than O-SOFC due to higher Nernst potential of H-SOFC and higher ionic conductivity of the proton conducting electrolyte [10,11,16]. However, according to the author's best knowledge, no experimental comparison of H-SOFC and O-SOFC with hydrocarbon fuels has been reported in the literature.…”

Mathematical Modelling of Proton‐Conducting Solid Oxide Fuel Cells and Comparison with Oxygen‐Ion‐Conducting Counterpart

“…A higher CO content in the fuel requires more H 2 O supply, resulting in a higher anode concentration overpotential. Furthermore, other chemicals, such as methane, ethanol and ammonia, can also be used as fuels in an H-SOFC [36][37][38]. Similar to synthesis gas (CO + H 2 ), the use of other fuels will involve complex gas transport and chemical reactions.…”

Analysis of planar solid oxide fuel cells based on proton-conducting electrolyte

“…However, there are currently limited studies related to the modeling and analysis of SOFC-H + stacks and systems [22][23][24][25]. Further, most studies investigate the theoretical performance of the SOFC-H + without fully considering the irreversible losses found in actual fuel cell operations [22][23][24]. An electrochemical model is therefore required to predict the performance of SOFC-H + to enable the improved analysis and design of fuel cell systems based on this technology [3,6,7].…”

“…To date, many studies have focused on SOFC technology using oxygen-ion conducting electrolytes (SOFC-O 2− ) because of the chemical stability and low electrical resistance of oxygen-ion conductors, e.g., stabilized zirconia and doped ceria [1][2][3][4][5][6][7][8][9][10]. However, as solid oxides with proton conduction have been discovered and developed [11][12][13][14][15][16][17], a number of the studies related to the use of such proton-conducting SOFCs (SOFC-H + ) have been reported [11,[18][19][20][21][22][23][24][25]. When a proton-conducting electrolyte is used, water vapor is produced at the cathode side.…”
