Abstract:

Solid Oxide Fuel Cells (SOFC's) are complex electrochemical devices whose designs require consideration of mass transport, electronic and ionic conductivity, and thermal management. Traditional SOFC fabrication techniques produce electrodes whose random pore geometries are not necessarily ideal with respect to the cell's functional requirements. This paper details initial experimentation involving novel multi-material direct-write printing techniques whose aim is to produce anode and cathode layers in which pore size and shape have been tailored to improve cell performance. Optical and electron microscopy are used to characterize the direct-write printed porous electrodes.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
