Novel high-temperature proton and mixed-proton electron conductors for fuel cells and H2-separation membranes
The project develops proton-conducting and mixed proton-electron conducting materials stable in atmospheres containing CO2. The materials will be used in future energy-efficient and environmentally-friendly technologies based on hydrogen, primarily fuel cell, electrolysis and gas-separation technologies. The materials can also be used for CO2 capture.
Solid oxide fuel cells convert the chemical energy of fuel into electricity. Oxides containing moblie hydrogen ions (high-temperature proton conductors) can perform the same function. An oxide of composition BaZr(1-x-y)CexYyO(3-0) (BCZY) has adequate electrical conductivity, mechanical strength and stability to CO2, but requires a temperature of 1700 Degr. Celsius for its fabrication, with consequences for fabrication cost. In this project, compositions with Ni and Co as sintering aids sintered satisfactorily at 1450 deg. Celsius. These oxides were characterised as fuel cell materials and found to be promising for applications at ca. 600 deg. Celsius. (Energy 11)
