Development and production of experimental samples of the solid oxide fuel cell (SOFC) interconnect made of a titanium-based alloy and conducting short-term experiments for its approbation under SOFC operation conditions
popup.description2
The present research work was devoted to development of the solid oxide fuel cell (SOFC) interconnects system made from titanium alloy was and testing under SOFC operating conditions (800℃, H2, O2). The system used by the Turkish partners under the NATO G5949 project was chosen as the basis for the design of the SOFC interconnect system. The manufactured system of interconnects allows conducting studies on the electrical properties of SOFCs with a size of 50x50mm under different operation conditions (gas supply speed, temperature 600-800℃).
Comparative studies of the interconnect systems made of heat-resistant titanium alloy and stainless steel (Crofer APU22) were performed during short-term tests (5 hours) of the electrical properties of several SOFCs under the same conditions. The average values of maximum power of SOFCs tested using Crofer APU22 interconnects were found to be 0.33 W/cm2 and titanium alloy interconnects to be 0.29 W/cm2. In all cycles of short-term SOFC studies on titanium alloy interconnects, no failures were detected. The difference in values of SOFC performances were not significant and were at level of the experimental error.
The obtained data indicated the promising application of the Ti-based SOFC interconnects. This should solve the problems associated with the poisoning of SOFC components with chromium compounds during long-term operation of CHP with Crofer APU22 interconnects (traditional interconnects). Further work will be focused on long-term studies of the developed interconnect systems under the SOFC operating conditions in order to study degradation processes of the materials.
