High Temperature Electrolysis of Water in a “Reversible” Solid Oxide Fuel Cell

Abstract

Electrocatalytic properties of ceramic SrTiO3-based composites were evaluated for both oxidation of hydrogen and decomposition of water in a three electrode configuration setup. The tests were performed at atmospheric pressure in the temperature range 800-950oC while varying steam partial pressure from 3 to 85 kPa. SrTiO3-based ceramic composites were found to be effective catalysts for both reactions and maintain good stability over the wide range of water partial pressures. Nickel-YSZ electrode was found to degrade rapidly at high water contents in the fuel gas.
