Summary:According to the present invention, an electrolyte composite for a solid oxide fuel cell contains a compound of formula 1: (La_(1-x) Sr_x)_ yMnO_3 as a sintering additive and a compound of formula 2: R_mCe_(1-m)O¬_(2-m/2). In formula 1, x is 0.1 to 0.5, and y is greater than 0 and less than or equal to 0.95. In formula 2, R is one or more selected from Gd, Sm, and Y, and m is 0.05 to 0.2. In addition, the present invention has an energy-saving effect in a preparing process by lowering the simultaneous sintering temperature of an anode electrode and electrolyte. 본 발명에 의한 고체산화물 연료전지용 전해질 복합체는 화학식 1의 화합물을 소결첨가제로 포함하며, 화학식 2의 화합물을 함유하는 것을 특징으로 한다. [화학식 1] (La(1-x)Srx)yMnO3 화학식 1에서, x는 0.1 내지 0.5이며, y는 0 초과 0.95 이하이다. [화학식 2] RmCe(1-m)O(2-m/2) 화학식 2에서, R은 Gd, Sm 및 Y에서 선택되는 하나 또는 둘 이상이며, m은 0.05 내지 0.2이다.
