Abstract

A single solid oxide fuel cell (SOFC) with a La_0.8Sr _0.2Ga_0.83Mg_0.17O_2.815 (LSGM) electrolyte 200 μm thick with H₂ as fuel gave 1.4 W/cm² peak power density at 800°C. With a La_0.4Ce_0.6O _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.
