Abstract
A single solid oxide fuel cell (SOFC) with a La0.8Sr 0.2Ga0.83Mg0.17O2.815 (LSGM) electrolyte 200 μm thick with H2 as fuel gave 1.4 W/cm2 peak power density at 800°C. With a La0.4Ce0.6O 1.8 (LDC) buffer layer 20 μm thick between the electrolyte and the two electrodes, a 30-day test showed essentially no degradation of the output power. The tests demonstrated the feasibility of an SOFC operating at temperatures T < 800°C with LSGM as the electrolyte. Moreover, an LSGM electrolyte 200 μm thick with 20 μm LDC buffer layers on either side offers a convenient test bed for the exploration of new electrode materials.
