Abstract:
The effect of anode microstructure and its corresponding electrochemical performance is investigated. Two distinctive anode microstructures were fabricated by using inkjet printing. One has conventional microstructure made by printing suspension inks of CGO/NiO (50wt%:50wt%), whereas the other one has fine CGO coating dispersed evenly on the surface of NiO. The latter microstructure was made by printing CGO Sol based ink on a pre-deposited NiO (700nm powder, 10µm in thickness) functional layer. AC impedance test were conductive on a symmetrical cell under hydrogen. The result reveal fine CGO coated anode has much lower polarisation due to a larger triple phase boundary per volume. The result shows inkjet printing technique provides a cost effective route for SOFC processing.
