Abstract

In this work, a series of planar anode billes for a solid oxide fuel cell based on NiO/Ce0.8Gd0.2O2 (NiO/GDC) was fabricated using the microdroplet 3D printing method with a pneumatic metering valve. The porosity and shrinkage coefficient during sintering of the anode billes, depending on the method of fabrication, have been investigated.

Anode billes were reduced in a hydrogen flow, and the effect of printing parameters on the morphological, structural, and electrochemical characteristics of NiO/Ce0.8Gd0.2O2 cermet was studied. The use of 3D printing was found to increase the porosity of the Ni/GDC composite from 7 to 23% as compared to that of the sample prepared by means of casting, while the value of electrical conductivity, (2.82 ± 0.06)·103 S/cm, remains high.
