Densification behavior of yttria-stabilized zirconia powders for solid oxide fuel cell electrolytes
Journal of Advanced Ceramics, 2018 Yttria-stabilized zirconia (YSZ) is the most common electrolyte material for solid oxide fuel cells. Herein, we conducted a comparative study on the densification behavior of three different kinds of commercial 8 mol% YSZ powders: (i) TZ-8Y (Tosoh, Japan)
