| titleOfInvention | Method for synthesizing electrolyte powder based on complexation-freeze drying method and obtained electrolyte powder |
| abstract | The invention discloses a method for synthesizing solid oxide fuel cell electrolyte powder based on a complex-freeze drying method and the obtained electrolyte powder, which belong to the field of electrolyte synthesis. The synthesis method of the present invention uses citric acid and glycine as complexing agents when synthesizing the fluorite structure cerium oxide-based electrolyte powder with oxygen ion conduction. The complexing ability, ignition point and combustion heat of the two complexing agents are different. Adjusting the ratio and total amount of the double complexing agent can control the total metal ion concentration and the exothermic process during heat treatment. Stir at 60-90 ° C to obtain a metal ion complex solution, and then freeze and freeze-dry to obtain a metal ion complex solution. The dry skeleton of the ion complex is subjected to heat treatment to obtain pure-phase cerium oxide-based electrolyte powder. Since the addition of glycine can act as a combustion agent, combustion can occur after the heating temperature exceeds the ignition point, and the phase-forming temperature is reduced; The synthesis method does not need to adjust the pH value of the solution during the synthesis process, greatly reduces the phase-forming temperature of the powder, and helps to improve the sintering activity of the powder. |
