Abstract

This study investigated the effects of patameters of phase inversion tape casting process on the skin-layer and finger-like layer structures of anode of solid oxide fuel cells (SOFCs). The skin-layer structure of anode was studied by controlling the slurry immersion approach during the phase inversion process. Consequently, the anode body with a smooth surface could be obtained when the slurry was immersed in deionized water with a constant speed, via tilted approach. Furthermore, the effects of solid content and polymer concentration on the anode structure were comprehensively studied. With the increase in solid content, the porosity and the size of channels gradually decreased. By contrast, the wall thickness of channel gradually increasesed. The anode with finger-like structure, prepared with a solid content of 65 wt% and polymer concentration of 25 wt%, exhibited the best suitable structure for gas diffusion, which is conducive to developing SOFCs based on finger-like structure.

固体氧化物燃料电池相变带铸造工艺参数的调整

研究了相变带铸造工艺参数对固体氧化物燃料电池阳极皮肤层和指状层结构的影响。在相变过程中，采用控制浆液浸入法研究阳极的皮层结构。因此，当浆料以等速倾斜方式浸入去离子水时，可以获得表面光滑的阳极体。此外，还全面研究了固体含量和聚合物浓度对阳极结构的影响。随着固含量的增加，孔隙率和孔道尺寸逐渐减小。而沟道壁厚逐渐增大。当固含量为65 wt%，聚合物浓度为25 wt%时，制备的指状阳极具有最佳的气体扩散结构，有利于基于指状结构的sofc的发展。

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
