The presented paper contributes to developing a new thermal control approach for solid oxide cell (SOC) stacks and systems. Integrating planar liquid metal heat pipes to the interconnector structure of the stacks targets a reduction of internal temperature gradients and an enhanced heat extraction from the stack. This work applies 3-D CFD-modelling to discuss the thermal effects of integrated heat pipes in solid oxide cell stacks, in order to evaluate the possible benefits in terms of temperature gradient reduction and heat removal as well as the resulting benefits for stacks and systems. The stack model set-up is described and its functioning is validated with experimental results from thermal short stack measurements with integrated heat pipe interconnectors. The simulation results are discussed with respect to the possible benefits for full-scale stacks of different cell size, in particular regarding internal heat recycling and the beneficial reduction of air ratios.

提出的论文有助于开发一种新的用于固体氧化物电池（SOC）堆栈和系统的热控制方法。将平面液态金属热管集成到堆叠的互连器结构中的目的是降低内部温度梯度并增强从堆叠的热量提取。这项工作采用3-D CFD模型来讨论固体氧化物电池堆中集成热管的热效应，以便评估在降低温度梯度和散热方面可能带来的好处，以及对堆和系统产生的好处。描述了烟囱模型的设置，并通过集成热管互连器的热短烟囱测量的实验结果验证了其功能。
