Abstract
The influence of water vapor in air on power generation characteristic of solid oxide fuel cells was analyzed by measuring cell voltage at a constant current density, as a function of water vapor concentration at 800° and 1000°. Cell voltage change was negligible at 1000°, while considerable voltage drop was observed at 800° accelerated at high water vapor concentrations of 20 wt % and 40 wt %. It is considered that La 2O3 formed on the (La0.8Sr02) 0.98MnO3 surface, which is assumed to be the reason for a large voltage drop.
