③报告简介:

报告一:Modeling is of key importance in fuel cell development beyond the current-state-of-the-art because it is beneficial to understand the mechanisms of various interacting phenomena and effects on the cell performance. It is also hard to measure the local parameters inside fuel cells, particularly inside the small scale functional materials. Modeling and simulation of charge transfer and electrochemical performance are critical to enable optimization of the geometry and performance. For macroscale modeling, the micro- and nano-structure related properties defining a porous media, e.g., the porosity and tortuosity and the specific area available for surface reactions are required. Thus the coupling of models valid at various scales is important for continued progress in the development of fuel cells. Within this paper both macroscale and micro-/nanoscale modeling approaches are presented for the fuel cell types SOFC (solid oxide fuel cell) and PEMFC (polymer electrolyte membrane fuel cell). In particular the electrodes, electrolyte and unit cells are considered. Some relevant results are provided.

报告二:Energy systems involve many components where fluid flow, heat and mass transfer, chemical and electrochemical reactions are the key transport processes. For design and development as well as investigation of innovative ideas, computational methods are of vital importance. CFD approaches based on the continuum hypothesis have been developed since the 1960s and today many commercial computer codes exist for applications. Nevertheless research is still needed not the least for turbulence modeling, complex geometries and parallel computing. As equipment are becoming very small in scale and important processes take place at nano or microscale, the continuum approach needs to be relaxed and non-continuum methods based on some form of coarse-grained molecular dynamics are needed. In this talk investigations of computational heat transfer, fluid flow and related transport phenomena applied to plate heat exchangers (PHEs), gas turbine heat transfer, and fuel cells (SOFC, SOEC, PEMFC) are highlighted.
