The invention is related to a metal-air current source and to its cathode. The cathode includes a base made of porous current-conducting material, permeable for molecular oxygen, to whose operating surface is applied a polymer complex compound of transition metal with the Schiff base, having a stack structure, in which the separate fragments of the said polymer compound are connected to each other through the donor-acceptor interaction, for example the compound of poly-[M(R,R'-Salen)], poly-[M(R,R′-Saltmen)] or poly-[M(R,R′-Salphen)] type.

Cathode for metal-air current sources and metal-air current source with such cathode

A method for creating a metal-carbon composite. In one embodiment, the method includes the steps of providing a polymer Schiff base transition metalfilmcomplexprecursorfilmhaving a chemical structure of the formula [M(Schiff)]and a recurring unit and a transition metal selected from the group consisting of nickel, palladium, platinum, cobalt, copper, iron; Schiff is a tetradentate Schiff base ligand selected from the group consisting of Salen (residue of bis(salicylaldehyde)-ethylenediamine), Saltmen (residue of bis(salicylaldehyde)-tetramethylethylenediamine, Salphen (residue of bis-(salicylaldehyde)-o-phenylenediamine), a substituent in a Schiff base is selected from the group consisting of H&#x2014;, and carbon-containing substituents, preferably CH&#x2014;, CH&#x2014;, CHO&#x2014;, CHO&#x2014;, and Y is a bridge in a Schiff base depositing the polymer Schiff base transition metal precursor film onto a support substrate; and heating the polymer Schiff base transition metalcomplexprecursor film and support substrate in a furnace in an inert atmosphere.
