PORTABLE CURRENT SOURCE Russian patent published in 2010 - IPC H01M8/00 B82B1/00 

FIELD: electricity.

SUBSTANCE: portable current source includes membrane electrode unit made on the basis of solid four-layered gradient porous structure representing the plate from porous non-conducting material the pores of which are filled with ion-conducting electrolyte 6M KOH. To one surface of the plate there applied is anion-exchange membrane and cathode catalyst layer containing manganese oxide in the form of nano-particles on porous carrier, and to the other surface there applied is hydrophilic layer of anode catalyst, which represents Ni-Ru-F alloy having the shape of nano-particles on porous carbon carrier; at that, layer of cathode catalyst is adjacent to gas-diffusion layer made from porous tetrafluoroethylene, and layer of anode catalyst is adjacent to the chamber filled with liquid fuel representing borohydride of alkali metal in alkali solution of gel electrolyte including secondary fuel chosen from polyatomic alcohol, such as glycerine, methyl cellosolve as thickener, and perfluorinated connection.

EFFECT: increasing oxygen concentration, reducing ohmic losses and preventing crossover of boron hydride ions to cathode owing to anion exchange membrane being used.
