Infiltration of commercially available, anode supported SOFC’s via inkjet printing

摘要: Commercially available anode supported solid oxide fuel cells (NiO-8YSZ/8YSZ/LSCF- 20 mm in diameter) were infiltrated with gadolinium doped ceria (CGO) using a scalable drop-on-demand inkjet printing process. Cells two different precursor solutions—water based or propionic acid based. The saturation limit of the 0.5 μm thick supports sintered at 1400 °C was found to be approximately 1wt%. No significant enhancement power output recorded practical voltage levels. Microstructural characterisation carried out after electrochemical performance testing high resolution scanning electron microscopy. This work demonstrates that despite feasibility achieving CGO nanoparticle infiltration into thick, commercial SOFC anodes simple, low-cost and industrially procedure other loss mechanisms dominant. Infiltration model symmetric ink demonstrated reductions polarisation resistance possible.
