High temperature-type proton conductive solid oxide fuel cells using various fuels

Using a high temperature-type proton conductive solid electrolyte based on SrCeO3, the performances of various types of fuel cells were studied at 800 to 1000°C. Ethane, carbon monoxide and ethanol were used as the fuel. In the ethane-air fuel cell, the simultaneous generation of electricity and ethylene could be carried out without oxidizing ethylene into carbon dioxide. These cells worked stably and the major limitation of the cell system was the resistance of the solid electrolyte.
