Outline of Final Research Achievements

This research aims to fabricate the three-dimensional microstructure of triple phase boundary in solid oxide fuel cells, in which each network is ideally connected, by using 3D printers. Three kinds of ink slurry, which are electrolyte, electrode and filler to form the pore network after sublimation, are developed to ensure proper jet of each slurry and fast fabrication of microstructure. In order to optimize concentration, dispersion and viscosity, main solutes, solvents and dispersants are mixed and orchestrated in various blend ratios. Eventually, we succeeded in fabricating the around 25 micrometers microstructure of multi-layered triple phase boundary with completely connected three networks.
