A critical challenge to the commercialization of clean and high-efficiency solid oxide fuel cell(SOFC)technology is the insuf-ficient stack lifespan caused by a variety of degradation mechanisms,which are associated with cell components and chemical *** components related degradation refers to thermal/chemical/electrochemical deterioration of cell materials under operating conditions,whereas the latter regards impurities in feedstocks of oxidant(air)and reductant(fuel).This article provides a thermodynamic perspective on the understanding of the impurities-induced degradation mechanisms in *** discussion focuses on using thermodynamic ana-lysis to elucidate poisoning mechanisms in cathodes by impurity species such as Cr,CO_(2),H_(2)O,and SO_(2) and in the anode by species such as S(or H_(2)S),SiO_(2),and P_(2)(or PH_(3)).The author hopes the presented fundamental insights can provide a theoretical foundation for search-ing for better technical solutions to address the critical degradation challenges.

资本监管是我国金融监管部门对商业银行进行监管的最重要途径。以往将银行信用风险承担行为过程进行分阶段研究的实证分析较少,选取的衡量信用风险和资本监管层次的指标有待丰富。利用我国52家商业银行2013—2020年数据,运用资本监管影响信用风险事前、事中和事后承担行为的研究框架,研究了资本监管中银行指标达标前和达标后所受到的监管压力对信用风险承担行为的影响。结果显示:资本监管对信用风险事前和事后承担行为的影响效果较明显,而对于信用风险事中承担行为发挥的监管效益有待提高;资本充足率的监管比核心一级资本充足率监管更为有效。
