The synthesis and electrochemical characterisation of T* based La0.84Sm0.96Sr0.2CuO4 (LSSCu) has been carried out in order to use as a cathode material for intermediate temperature solid oxide fuel cell application. XRD studies shows, the phase pure material and matches with the JCPDF (# 79-1861), belong to space group of P4/nmm. The electrical conductivity value decreases from 52 Scm(-1) at room temperature to 18.3 Scm(-1) at 850 degrees C showing metallic behaviour in all temperature range. A decrease in conductivity, decreasing the partial pressure of oxygen implying the above material is p-type conductor. The Coefficient of thermal expansion value measured from Dilatometry is 14.4 * 10 (-6) K-1 which matches with La0.9Sr0.1Ga0.8Mg0.2 (LSGM). Symmetrical cell testing results shows that the area specific resistance is 0.02 Omega.cm(2) at 800 degrees C when the 1:1 weight ratio of the LSSCu and LSGM composite was screen printed on LSGM electrolyte and sintered at 900 degrees C for 1 hr.
