alkaline fuel cells

Catalysts for oxygen reduction in the alkaline electrolyte based on multi-walled carbon nanotubes modified with urea and phthalocyanines of iron, cobalt and palladium were synthesized and studied. Physicochemical studies of the surface of the synthesized materials were carried out using porosimetry, Raman spectroscopy, X-ray phase analysis and X-ray photoelectron spectroscopy. The catalyst doped with metal phthalocyanines (MWCNT(Urea)_CoPc_FePc_Pd) has the largest surface area.

In this work the main principles used in the development of portable power source based on fuel cells with indirect oxidation of sodium borohydride are described, the general arrangement of this power source is shown, and its operating mechanism is described. The proposed power source has a number of advantages over existing portable power sources. The application of alkaline fuel cells enables to discard expensive solid-polymer electrolyte, catalysts and constructional materials that will lead to significant decrease of the power source cost.
