In this article, we outline and review the methods that are currently used to simulate the micro/meso-scale flow and reactive transport processes in the porous catalyst layers (CLs) of a fuel cell. The approaches beyond the atomic scale (molecular dynamics) and below the conventional continuum...

A literature study is performed to compile the state-of-the-art, as well as future potential, in SOFC modeling. Principles behind various transport processes such as mass, heat, momentum and charge as well as for electrochemical and internal reforming reactions are described. A deeper...

A finite volume method based computational fluid dynamics model has been developed and applied for a cathode-supported planar solid oxide electrolysis cell (SOEC) operating in cross-flow configuration arrangement. The performance behavior, in terms of current density, temperature distribution...

The periodical fluctuation phenomenon appears in coal mine and other fields of government safety supervision. The paper provides a theoretical explanation by building an evolutionary game model between coal mine industry and governmental supervision institutions. Moreover, the paper provides a...

The concept of zero emission contributes significantly to sustainable development. China is planning to build a circular economy pilot area with zero emissions in the Western Qaidam Basin. The paper discusses some theoretical and practical issues in the regional planning. In particular, the...
