  • Cathode structures for solid oxide fuel cells
    Publication number: 20090142642
    Abstract: Cathode structures for low temperature solid oxide fuel cells are provided. The cathode structures include thin dense mixed ionic electronic conducting (MIEC) films. MIEC materials include materials with perovskite structures, such as LSCF. The thickness of the MIEC film is determined by minimizing the sum of the electronic and ionic resistances. Specific functions for the electronic and ionic resistances in terms of device and physical parameters are also provided. Pulsed laser deposition is used for the fabrication of the MIEC film and the electrolyte layer.
