Multilayer structure based on thick films for low temperature (600 °C) fuel cell

Development of preparation technology of multilayered structures based on thick films for low temperature (600°C) fuel cell.

Area of applications

Low-temperature (600 °C) fuel cells, oxygen sensors.

Brief description

Multilayer system that consists of thick porous films of anode and cathode materials and separated by a dense electrolyte film have been developed. Chemical composition has been optimized and chemical stability of such multilayer systems has been studied. Low-temperature (600 °C) fuel cell based on multilayer systems has been developed and its electrical properties has been studied

Expected results

A multilayered system consisting of porous films of anode and cathode materials, connected thought a dense electrolyte film, will be manufactured by the method of tape casting. Using multilayer system prepared, an experimental model of the fuel cell will be made and tested.

Advantages

The low-temperature (600°C) fuel cell produced has higher characteristics compared to a commercial analogue. Thus, when fuel cell uses a model fuel gas, maximum specific power of developed one demonstrated a 4.2 mW / cm², while of commercial one demonstrated only 2.8 mW/cm².

Competitors

Siemens Westinghouse Power Corp., Global Thermoelectric, Argonne National Laboratory

Project development

The technology for preparation of vacuum-dense polycrystalline bulk materials, gas-tight thin and thick films with a high level of oxygen conductivity in the region of average temperatures (500-600 °C) based on zirconium oxide with a structure of cubic fluorite, stabilized with complex scandium-containing additives was developed. A low-temperature (600°C) fuel cell has been manufactured, which has the highest characteristics compared with its commercial counterpart.
