Abstract

An anode-support microtubular solid oxide fuel cell (MTSOFC) using an intermediate ring-shaped electrode collector is simulated using COMSOL Multiphysics software to investigate current density distribution and mass transfer in both power generation and electrolysis modes. The cell is converted to power generation mode during continuous electrolysis, and the electrochemical performance of MTSOFC is tested to study the effect of electrolysis on the power generation performance. The power density output of the MTSOFC decreases from 250 to 150 mW cm⁻² after only 40 h of continuous electrolysis. The microstructural changes in different regions during operation are observed through posttest analysis conducted on the fuel inlet, electrochemical reaction concentration region, and fuel outlet of the microtubular cell. The local agglomeration of nickel occurs in the concentrated region of the electrochemical reaction, while the coarsening of nickel oxidation mainly takes place at the fuel inlet and outlet.

连续电解对使用中间环形集流体的微管氧化物燃料电池发电性能的影响

使用 COMSOL Multiphysics 软件模拟了使用中间环形电极集流器的阳极支撑微管固体氧化物燃料电池（MTSOFC），研究了发电和电解模式下的电流密度分布和传质情况。该电池在连续电解过程中转换为发电模式，并测试了 MTSOFC 的电化学性能，以研究电解对发电性能的影响。在连续电解 40 小时后，MTSOFC 的功率密度输出从 250 mW cm-2 降至 150 mW cm-2。通过对微管电池的燃料入口、电化学反应浓缩区和燃料出口进行后测分析，观察到了运行过程中不同区域的微观结构变化。镍的局部团聚发生在电化学反应的集中区域，而镍氧化的粗化主要发生在燃料入口和出口。
