Abstract
A thin wafer comprising through holes filled at least partially with conductive carbon nanotubes generally oriented transversally to the wafer. A fuel cell comprising, in a thin wafer, a through hole filled with an electrolyte surrounded with barriers of carbon nanotubes generally oriented transversally to the wafer.
Claims20
A thin wafer comprising a plurality of through holes filled at least partially with conductive carbon nanotubes generally oriented transversally to a surface of the wafer.
A fuel cell comprising:
- a thin wafer,
- a through hole within the thin wafer, said through hole being filled with an electrolyte surrounded with barriers of carbon nanotubes generally oriented transversally to the wafer.
A method for manufacturing a fuel cell, comprising the steps of:
- forming through openings in a silicon wafer;
- making the silicon porous close to the openings;
- forming carbon nanotube barriers by growing carbon nanotubes in the through openings from a surface of the wafer towards the opposite surface;
- and
- hollowing portions arranged between two carbon nanotube barriers and;
- filling the hollowed portions with an electrolyte.

A fuel cell comprising:
- a wafer having a top surface and a bottom surface;
- a first through opening in the wafer extending from the bottom surface to the top surface, the first through opening being filled with conductive carbon nanotubes arranged longitudinally along the first through opening,
- a second through opening in the wafer extending from the bottom surface to the top surface, the second through opening being filled with conductive carbon nanotubes arranged longitudinally along the second through opening, and
- an electrolyte chamber containing an electrolyte and arranged between the first and second through openings.
