SINGLE-CHAMBER FUEL CELL AND METHOD OF PRODUCING CONDUCTING NANOCOMPOSITE MATERIAL THEREFOR Russian patent published in 2015 - IPC G01N27/08 H01M4/86 B82B1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to electronics and is intended to design devices which convert the chemical reaction of adsorbed molecules of a fuel gas (vapour) and oxygen (or air) into an electrical signal. The invention can be used to design compact batteries for electronic equipment in the form of single-chamber fuel cells, which consist of a working chamber having a fuel-gas mixture inlet and a gas outlet, inside of which there is a composite film with electrical contacts connected to an external load, the space between which is filled with a conducting material. The conducting material used is a nanocomposite material which consists of a non-conducting polymer film of polypropylene and conducting filler in the form of carbon nanotubes. Concentration of the carbon nanotubes with p-type conductivity is about 0.5-5% near the percolation threshold. The nanocomposite material may contain catalytic nanoparticles of Pt or Pd, or Rh, or Ru. Also disclosed is a method of producing a conducting nanocomposite material, which includes mixing carbon nanotubes and polymer material and then holding the nanocomposite material at external voltage of 4-10 V for 2-30 min in an atmosphere of saturated acetone vapour.

EFFECT: higher current density in the active layer.
