Summary

This paper describes an intermediate temperature solid oxide fuel cell (ITSOFC), based on porous La0.75Sr0.25Cr0.5Mn0.5O3 (LSCM) anode, La0.8Sr0.2Ga0.8Mg0.2O2.8 (LSGM) electrolyte, and porous La0.6Sr0.4MnO3 (LSM) cathode. Using different amounts of poreformers, binders and firing temperatures, the porosity of the anode was optimized while still retaining good mechanical integrity. The effect of cell operation condition under saturated hydrogen fuel on the SOFC open circuit voltage (OCV) was also investigated. It is shown that 20 mL/min flow rate of saturated hydrogen results in an initial OCV up to about 1.0V for a single cell. The cell was tested for more than 500 hours maintaining high values of OCV (0.9V). Increasing the hydrogen flow rate up to 200 mL/min, results in enhanced OCV values up to 0.99V.
