تأثیر دما و جو بر قدرت و مدول الاستیسیت از آنودای سلول سوختی اکسید جامد پشتیبانی می کند

In this study, the effect of reduction temperature on microstructural stability, high temperature strength and elastic modulus of Ni−YSZ anode supports were investigated. The statistical distribution of strength was determined from a large number of samples (∼30) at each condition to ensure high statistical validity. It is revealed that the microstructure and mechanical properties of the Ni−YSZ strongly depend on the reduction temperature. Further studies were conducted to investigate the temperature dependence of the strength and elastic modulus for both the unreduced and reduced Ni(O)−YSZ anode supports. With increasing temperature, the strength and elastic modulus of the reduced Ni−YSZ specimens drop almost linearly. In contrast, the strength and elastic modulus of the unreduced NiO−YSZ remain almost constant over the investigated temperature range. Compared to the NiO-YSZ, a significantly lower strength and elastic modulus of the reduced Ni-YSZ is observed; while reduction leads to a remarkable increase in failure strain of the anode support.
