PERFORMANCE OF PLANAR SINGLE-CELL LANTHANUM GALLATE BASED SOLID OXIDEFUEL-CELLS

A novel synthesis of high purity, single phase strontium-magnesium dop ed lanthanum gallate through a nitrate route is described. The prepare d powder is formed into planar monolithic elements by uniaxial pressin g followed by isostatic pressing and sintering. XRD analysis of the si ntered elements reveal no detectable secondary phases. The performance of the electrolyte in solid oxide fuel cells (SOFC) with three differ ent anode/cathode combinations tested at 700 degrees C with respect to the J-V and power density is reported. The data show that the charact eristics of this SOFC are strongly dependent on the particular anode/c athode system chosen. (C) 1998 Minister of Natural Resources, Canada.
