Abstract
A method of making a ceramic powder (22), for producing the ion conductive electrolyte of a high temperature fuel cell, involves (A) mixing a metal alcoholate solution (12) and a metal salt solution (13) and adding water to form a gel (14); (B) thermally decomposing the gel to form a xerogel (18); (C) pulverizing the xerogel to a ceramic powder (22); and (D) calcining the powder (22). Also claimed is a high temperature fuel cell with an electrolyte produced by the above method, the electrolyte preferably containing 8-13 mol% of one or more of scandium oxide (Sc2O3), yttrium oxide (Y2O3) and ytterbium oxide (Yb2O3).
