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.

针对农村综合能源系统中平抑间歇式可再生能源波动造成的生态养殖热电联产系统大范围出力波动问题,提出了一种计及储能和热电联产快慢协同的农村综合能源系统分层控制框架。首先,分析了生态养殖过程中的废弃物和沼气发电的多能耦合特征及其典型结构。进而,建立考虑光伏发电、沼气热电联产、生物质储能等的生态综合能源系统模型,提出基于饱和滤波器的快慢协同控制系统。最后,建立考虑经济调度和快慢协调控制的分层框架,兼顾最小化外购电成本需求以及光伏和负荷不确定性对设备调控的影响。算例分析表明,所提调度策略能够有效降低运行成本,平抑光伏和负荷预测误差导致的热电联产出力频繁调整,帮助农村综合能源系统实现光伏发电的完全消纳。

Integrated circuits(ICs) and optoelectronic chips are the foundation stones of the modern information society. The IC industry has been driven by the so-called "Moore’s law" in the past 60 years, and now has entered the post Moore’s law era. In this paper, we review the recent progress of ICs and optoelectronic chips. The research status, technical challenges and development trend of devices, chips and integrated technologies of typical IC and optoelectronic chips are focused on. The main contents include the development law of IC and optoelectronic chip technology, the IC design and processing technology, emerging memory and chip architecture, brain-like chip structure and its mechanism, heterogeneous integration, quantum chip technology, silicon photonics chip technology, integrated microwave photonic chip, and optoelectronic hybrid integrated chip.
