Anode supported (ASC) and electrolyte supported cells (ESC) represent the most common cell concepts in solid oxide fuel cell (SOFC) technology. In ASCs, mechanical manageability is provided by a porous nickel/yttria-stabilized zirconia (Ni/YSZ) substrate, whereas in ESCs a self-supporting dense YSZ electrolyte is applied. Naturally, the electrical loss contributions arising in ASCs and ESCs differ in quantity, leading to different temperature profiles within planar SOFC stacks.

A two-dimensional, finite element method model was developed which considers the underlying chemical and physical processes, and calculates both the electrical performance and the thermal distribution of planar SOFC stack layers operated with reformate fuels. It was then validated by comparing simulation results with extensively measured (i) temperature profiles in SOFC stacks, (ii) gas composition changes along the fuel gas channel of planar ASCs, and (iii) current-voltage characteristics in a temperature range from 650 °C to 800 °C.

The subsequent numerical study reveals (i) the different performances of ASC and ESC, (ii) the impact of operation conditions on performance and temperature profile and (iii) how the individual loss contributions generate temperature distributions in the stack layer.

阳极支撑（ASC）和电解质支撑电池（ESC）代表了固体氧化物燃料电池（SOFC）技术中最常见的电池概念。在ASC中，通过多孔的镍/氧化钇稳定的氧化锆（Ni / YSZ）基板提供机械可管理性，而在ESC中，则使用自支撑的致密YSZ电解质。自然地，在ASC和ESC中产生的电损耗贡献在数量上是不同的，从而导致平面SOFC堆栈内的温度分布不同。

建立了二维有限元方法模型，该模型考虑了潜在的化学和物理过程，并计算了使用重整燃料运行的平面SOFC堆层的电性能和热分布。然后，通过将模拟结果与广泛测量的结果进行比较，以对其进行验证：（i）SOFC烟囱中的温度曲线；（ii）沿平面ASC的燃料气体通道变化的气体成分；（iii）650°C温度范围内的电流-电压特性C至800°C。

随后的数值研究揭示了（i）ASC和ESC的不同性能，（ii）操作条件对性能和温度曲线的影响，以及（iii）各个损耗贡献如何在堆叠层中产生温度分布。
