Power Injection Molding (PIM) gives the possibility to produce ceramic parts with fine details at an industrial rate. It is thus one possible approach to reduce the fabrication costs of Solid Oxide Fuel Cells (SOFC). This work presents fabrication and electrochemical characterization results of injection-molded structured anode-supported SOFCs.

Planar anode-supported SOFC with fine details have been produced by injection molding of nickel oxide (NiO) and yttria-stabilized zirconia (YSZ). The fine details will ensure a good gas transport on the fuel side. After YSZ electrolyte deposition using spin coating process, the half cell is co-sintered. Electrochemical test is done with a lanthanum-strontium manganite (LSM)-YSZ cathode. The performance of the cell is comparable to previous anode-support at 0.45 W cm-2 at 0.6 V and 810°C. Long term galvanostatic test shows a degradation rate of about 1.1 % per 1000 h. Electrical impedance spectroscopy (EIS) and energy dispersive X-ray spectroscopy (EDS) conclude on cathode degradation due to Cr and S poisoning.

This paper is the first published electrochemical test of an SOFC produced via powder injection molding (PIM) process. These first results are very promising for using PIM fabrication process in the SOFC field.
