Evaluation of TiO2-glass composites as interconnector material for solid oxide electrolyte fuel cells
- 39 Downloads
Electronically conducting interconnector materials are required to connect consecutive anodes and cathodes in high-temperature solid oxide fuel cells. Nb-doped TiO2-glass composites, prepared by cold pressing and sintering in air above 1200° C, possess adequate conductivity and resistance to oxidizing and reducing atmospheres, as well as compatibility with Y2O3-doped ZrO2. They thus show promise as interconnector materials.
