Title:
HIGH POWER DENSITY SOLID OXIDE FUEL CELLS HAVING IMPROVED ELECTRODE-ELECTROLYTE INTERFACE MATERIAL
Document Type and Number:
WIPO Patent Application WO2002021625
Kind Code:
A3
Abstract:
A tubular fuel cell (10) contains an air electrode (24), an electrolyte (20), and a fuel electrode (12) where an interlayer material (22) is disposed between the air electrode and the electrolyte, the interlayer (22) containing a two-phase particle mixture, where the particles have a size range from 0.5-5 micrometers, but where at least 50 wt % of the particles are less than 3 micrometers and where the interlayer (22) is from 10-40 micrometers thick and from 5-50% porous.
