Sub-Micron Electrolyte Thin Film for Solid Oxide Fuel Cells


Stanford Reference:

02-135


Abstract


This patented electrolyte fabrication method is designed for deposition of low-cost, ultra-thin metal oxide film on a porous substrate. The simple, clean process prevents gas crossover and generates a low-resistance electrolyte that can operate temperature below 500oC. This electrolyte could be used to create a high efficiency solid oxide fuel cell.

Applications


  • Solid oxide fuel cells - fabrication of ultra-thin film electrolyte

Advantages


  • High efficiency :
    • low ionic resistance material from metal-oxidized electrolyte and nano-porous gamma-alumina substrate
    • no gas crossover
  • Simple and clean fabrication - DC-magnetron sputtering in Ar gas
  • Lower cost of sputtering target materials
  • Lower temperature fuel cell operation
