A tubular fuel cell ( ) contains an air electrode ( ), an electrolyte ( ), and a fuel electrode ( ) where an interlayer material ( ) is disposed between the air electrode and the electrolyte, the interlayer ( ) 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 ( ) is from 15-40 micrometers thick and from 5-50% porous.

High power density solid oxide fuel cells having improved electrode-electrolyte interface modifications

An electrochemical cell is made having a porous fuel electrode (16) and a porous air electrode (13), with solid oxide electrolyte (15) therebetween, where the air electrode surface opposing the electrolyte has a separate, attached, dense, continuous layer (14) of a material containing cerium oxide, and where electrolyte (16) contacts the continuous oxide layer (14), without contacting the air electrode (13).
