Abstract

A new concept of solid oxide fuel cell (SOFC), recently proposed, using simultaneously the same material (La0.75Sr0.25Cr0.5Mn0.5O3-delta, LSCM), as both, anode and cathode, has been verified. The performance of such new design, symmetrical fuel cells (SFCs). could be improved by using a YSZ/CGO-based composite. The optimum ratio to minimise the series and the polarisation resistances (R-p) under reducing conductions was 1: 1. This composition renders improved RP values by a factor of 2 at 950 degrees C in flowing H, in comparison to LSCM-YSZ composites. Thus, the use of a mixed composite (YSZ-CGO) will allow to extend the applicability of LSCM at temperatures lower than 850 degrees C. LSCN1-(YSZ-CGO) based SFCs offer promising performances, e.g., 0.4 W cm(-2) at 950 degrees C using humidified H, as fuel. (c) 2007 Elsevier Ltd. All rights reserved.
