Laser machining of nickel oxide–yttria stabilized zirconia composite for surface modification in solid oxide fuel cells

Laser machining of the nickel oxide–yttria-stabilized zirconia (NiO–YSZ) composite in Solid Oxide Fuel Cells (SOFCs) may be an effective approach to enlarge the electrode–electrolyte interface and improve the cell performance. However, laser energy can cause thermal damage to the composite surface d...
