英文摘要	an anode-supported micro-tubular solid oxide fuel cell (sofc) is analyzed by a two-dimensional axisymmetric numerical model, which is validated with the experimental i-v data. the temperature distribution generated by the thermo-electrochemical model is used to calculate the thermal stress field in the tubular sofc. the results indicate that the current transport in the anode is the same at every investigated position. the stress of the micro-tubular cell occurs mainly because of the residual stress due to the mismatch between the coefficients of thermal expansion of the materials of the membrane electrode assembly. the micro-tubular cell can operate safely, but if there is an interfacial defect or a high enough tensile stress applied at the electrolyte, a failure can arise.
