NOVELTY - A solution (A) is prepared using lanthanum oxide, strontium nitrate and cobalt nitrate and citric acid. Citric acid solution and metal ion are added to deionized water and aqueous ammonia is added to adjust pH to 3-6 to obtain solution (B). Tetrabutyl titanate and absolute ethyl alcohol are mixed to obtain solution (C). The solutions (B, C) are mixed and heated, and mixed with solution (A) to obtain transparent solution. The transparent solution is heated to obtain a sol. The sol is dried, burnt, ground and calcined to obtain lanthanum-based strontium titanate anode material.    USE - Manufacture of lanthanum-based strontium titanate anode material for solid oxide fuel cell.    ADVANTAGE - The anode material with small powder grain diameter is manufactured economically by a simple process.    DETAILED DESCRIPTION - Lanthanum oxide is dissolved in deionized water, and concentrated nitric acid is added to obtain transparent solution. Strontium nitrate and cobalt nitrate are added to obtain light red transparent solution. Citric acid is added and aqueous ammonia is added to adjust the pH to 3-6 to obtain solution (A). The addition amount of citric acid is 1000-2000 ml for each mol of the complex. Citric acid solution and metal ion are added in the mol ratio of 1.5-3:1 are added to deionized water and aqueous ammonia is added to adjust the pH to 3-6 to obtain solution (B). Tetrabutyl titanate used as titanium source and absolute ethyl alcohol are mixed to obtain solution (C). The solution (B) and solution (C) are mixed and heated in a water bath at 70-90 degrees C for 30-60 minutes to obtain clean solution (D). The solution (A) is added to the solution (D) to obtain light red transparent solution. The transparent solution is heated at 70-90 degrees C to obtain a sol. The sol is dried in an oven at 80 degrees C to obtain a dry gel. The dry gel is burnt at 250 degrees C to obtain a precursor powder. The precursor powder is ground and calcined in an electric furnace at 700-1300 degrees C to obtain lanthanum-strontium titanate anode material. The anode material has composition of formula: La0.3Sr0.7Ti1-xCoxO3|\( sigma ), where x is 0.01-0.07, ( sigma ) is 0-1. The mol ratio of the components added satisfies the relations: La2O3, Sr(NO3)2, C16H35O4Ti, Co(NO3)2.6H2O, La2O3:La0.3Sr0.7Ti1-xCoxO3 plus minus ( sigma )=0.15:1, Sr(NO3)2:La0.3Sr0.7Ti1-xCoxO3 plus minus ( sigma )=0.7:1, C16H35O4Ti:La0.3Sr0.7Ti1-xCoxO3 plus minus ( sigma )=1-x:1 and Co(NO3)2.6H2O:La0.3Sr0.7Ti1-xCoxO3 plus minus ( sigma )=x:1.
