Different types of self-supported SOFCs (i.e., anode-supported, cathode-supported and electrolyte-supported SOFCs) have been compared in literature mostly from technical point of view. In this study, the mentioned types of SOFCs are compared from technical and economic points of view simultaneously. In this regard, “maximum power density” and “material cost of PEN layer” are taken as objective functions. These functions are evaluated through numerical modeling and based on available cost data, respectively. The results illustrate that the cathode-supported SOFC is the optimal choice when power density is regarded alone. On the other hand, the electrolyte-supported SOFC is observed to be the optimal option when the material cost of PEN is considered as the only objective function. However, the anode-supported SOFC makes the best trade-off between the two objective functions when they are simultaneously taken into consideration. The results also indicate that the electrolyte-supported SOFC leads to a symmetrical and most uniform current density distribution as compared to the electrode-supported ones in which peak local current densities tend toward non-supporting side. The paper discusses in detail the reasoning for the mentioned observations.

阳极支撑,阴极支撑和电解质支撑的SOFC的技术经济比较

在文献中主要从技术角度比较了不同类型的自支撑SOFC(即阳极支撑,阴极支撑和电解质支撑的SOFC)。在这项研究中,同时从技术和经济角度比较了上述类型的SOFC。在这方面,将“最大功率密度”和“ PEN层的材料成本”作为目标函数。这些功能分别通过数值建模和可用成本数据进行评估。结果表明,当单独考虑功率密度时,阴极支撑的SOFC是最佳选择。另一方面,当将PEN的材料成本视为唯一的目标函数时,可以观察到电解质支持的SOFC是最佳选择。然而,当同时考虑两个目标函数时,阳极支撑的SOFC会在这两个目标函数之间取得最佳平衡。结果还表明,与电极支撑的SOFC相比,电极支撑的SOFC导致对称且最均匀的电流密度分布,在电极支撑的SOFC中,峰值局部电流密度趋向于非支撑侧。本文详细讨论了上述观察的原因。
