Modelling of high temperature direct methanol solid oxide fuel cells

Abstract: Summary Methanol is a promising fuel for solid oxide fuel cells (SOFCs). A 2D numerical model is developed to study a tubular direct methanol SOFC. The model fully considers the methanol decomposition reaction and water gas shift reaction in the anode, the electrochemical oxidations of H2 and CO, fluid flow and mass transfer in the cell. The model is validated by the direct methanol SOFC experiment. At a temperature of 1073 K, a peak power density of 1.2 W cm−2 is achieved, which is much higher than room tempe… Show more

“…Furthermore, liquid renewable hydrocarbon fuels such as methanol has high volume energy densities (1.6 × 10 4 kJ m −3 ), which is beneficial to fuel storage and the mobile applications at ambient pressure and temperature. Moreover, unlike other heavier alcohols like ethanol with the C -C bond in the molecular structures, the cleavage of C-H bonds is much easier for methanol through methanol thermal decomposition or steam reforming of methanol [5][6][7]. However, the utilization of hydrocarbon fuels in SOFC is hindered by serious carbon deposition on anode catalyst and the sluggish anode kinetics [8].…”

“…Hydrogen fuelled SOFC is pollution-free as the electrochemical reaction product is water. The SOFC is fuel-flexible and capable of utilising renewable fuels such as natural gas, biogas, syngas [4], methanol [5], ammonia [6] and methane [7] to reduce carbon release.…”

“…Importantly, unlike the battery, SOFC is an open system that thermally interacts with reacting gases; thus, the cell thermal state can be considerably influenced by gas conditions [35], especially for cathode air, but the cooling effects and thermal/electrical responses of air conditions have not been fully understood yet. Therefore, to fill this research gap, a validated mathematic model extended from our previous simulation works [36,37] is developed to further investigate the temperature gradient profiles in cell components, especially ceramic electrolytes. This work will be critically essential for the operating condition selection, structure design, and failure assessment of realistic SOFCs.…”
