This invention ensures sufficient gas diffusion and ion-conduction in a fuel cell catalyst electrode. This arrangement does not tequire a thick electrolyte layer to ensure sufficient transmission of ions, but enables sufficient oxygen to be fed to the catalyst. Patent number: US 6015635
Applicant: Uear Carbon Technology, USA Here a flexible graphite sheet has embedded ceramic fibres extending into the sheet, to provide permeability to gases so that it is useful as a fuel cell electrode.

can be tailored to match gas flow patterns and gradients. Further refinements can be achieved by varying the print pattern across the cell, and by using multiple layers to control both the depth and structure of the layers within the pattern.
