Development of composite electrode materials based on nickel oxide for additive manufacturing of fuel cells

Abstract

In this work, a new composition of a paste based on nanosized nickel oxide (NiO) for jet-based 3D printing has been developed and investigated. The optimal parameters of anode paste with necessary viscosity and NiO loading have been found for printing by using custom made laboratory 3D printer. Experiments have been carried out to print two-and three-dimensional test objects using the developed ceramic paste; printing modes have been investigated to fabricate objects of a given shape and size with laser sintering of the deposited layers. Experiments have been conducted for the selection of optimal temperature conditions for the post-processing of the printed samples.
