All-Ceramic SOFC Tolerant to Oxygen, Carbon and Sulfur

Abstract

Novel strontium titanate-ceria composite solid oxide fuel cell (SOFC) anode materials [1] were tested in single electrolyte-supported cells in the temperature range 600-900 degrees centigrade. Power densities of 420 to 350 mW/cm2 were generated in wet hydrogen at 0.7 Volt at 850 and 800 degrees centigrade, respectively. Moreover, ceramic anodes offered higher tolerance to oxidizing environments, sulfur-containing environments and hydrocarbons.
