A method of making a solid oxide fuel cell, comprising:
- preparing an SLT powder via solid state reaction using SrCO3, La2O3, and TiO2 precursors to form a calcinated SLT product;□
- dispersing the calcinated SLT powder with graphite and poly(vinylbutyral) (PVB) to form a homogeneous mixture;
- drying the homogenous mixture to form a dried product;
- pressing the dried product using a die;
- and
- bisque firing the pressed product.
