“…In SOEC mode, we used the experimental results of Iwahara et al [15] and the results from the model developed by Meng Ni et al [16]. In SOFC mode, we used experimental results of Iwahara's group [17] and the results from the model of Patcharavorachot et al [18], reporting current voltage characteristics for SOFC at three different temperatures: 1073 K, 1173 and 1273 K. In both cases the results demonstrated the validity of the analytical model. Similar results were obtained for the validation of the 3D model by our research group in a recent publication [19].…”

“…In [100] static air was used as oxidant, and the flow rate of fuel gas was about 40 mL min, but the fuel cell area was not given. In [76], fuel at molar flow rate of 2.27Á10 -5 mol s -1 , and air at molar flow rate of 2.27Á10 -5 mol s -1 were fed to a fuel cell with the following dimensions: 0.04 m long and 0.01 m wide. The inlet fuel and oxidant consisted of 10% H 2 (~3% H 2 O) and dry air, respectively.…”

Key Parameters of Proton‐conducting Solid Oxide Fuel Cells from the Perspective of Coherence with Models

et al. 2020

View full text Add to dashboard Cite

The paper presents a review of thermal, flow, and material parameters from the perspective of modeling proton‐conducting solid oxide fuel cells (H+SOFC). Comments are offered regarding key parameters selected through research of the literature, featuring mostly material‐related properties of electrolyte and electrodes. Some general relationships are proposed here for the purpose of modeling H+SOFC. The most important parameter is fuel cell operational temperature. Next to the temperature, partial pressures of hydrogen on both sides of H+SOFC impact mainly maximum voltage. The materials from which the fuel cell is built do not directly affect the operation of the fuel cell in the sense that they can be taken as fixed values. Indirectly, their influence can be seen in the resistances, that electrolyte conducts for proton flux and electrodes for electrons. In some cases, double ion/electron conductivity may occur.

“…The lower steam and higher hydrogen partial pressures of pSOFC compared to oSOFC favors better efficacy of pSOFC than oSOFC. Patcharavorachot et al [7] has developed and validate a design for j-V curve of pSOFC based on SrCeO3 electrolyte. They also investigated the cell performance with variation in thickness of electrolyte and electrodes in the cell.…”

Integrated hybrid power systems have become more and more important in recent years. The functioning of medium-temperature proton-conducting solid oxide fuel cell (pSOFC) hybrid system is proposed in this work. The combined system consists of a pSOFC stack, steam methane reformer, compressors, burners, heat exchangers and methanol synthesizing reactor. The excess waste heat of the burner is recovered using heat exchangers. Also, the unutilized hydrogen from SOFC is used for carbon reduction by methanol production. The functioning of configured system is explored by using Matlab/Simulink/Thermolib software. In pSOFC operation, stoichiometric ratio (Sto) of air is maintained 3 and Sto of hydrogen is varied between 1.4 to1.7. Results show that the benefit of carbon reduction depends on methanol production. By using water separator, the methanol production efficiency increases dramatically. In addition, hydrogen transfer membrane is used to increase stack efficiency and control the temperature of stack chamber and reformer. This further improves benefit of carbon reduction. The proposed hybrid system in this work can be used to power huge residential buildings and some factories.
