TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Apparatus: The electrolyzer is fuelled by an alkaline solution, and has a current density of 250-750 mA/cm2 (A is applied at a potential of 2.10-2.52 V).    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The metals are iron (Fe), ruthenium (Ru), cobalt (Co), iridium (Ir), nickel (Ni), palladium (Pd), molybdenum (Mo), or manganese (Mn). The catalysts are formed from Mn, Co, and Ni. The catalysts are supported on nickel powder, Vulcan XC-72R(RTM: activated carbon powder), nickel foam or other metal supports. The metal support is Ni or Co. Preferred Method: The hydrogen formed at the cathode and the oxygen that forms at the anode is collected.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The 4-(1-((phenyl-2,4- disubstituted)-hydrazine)-alkyl)-benzene-1,3-diol is a compound of formula (A). The 3,5-disubstituted phenol is a compound of formula (B). The metal salts comprise carboxylates, halogens and pseudohalogens, alcolates, acetylacetonates, formates, oxalates, malonates and analogous organic salts and their mixtures or carbonates and bicarbonates or their mixtures.R1=H, 1-10C hydrocarbon radical, possibly halogenated;R2, R3=electron-attractive group such as H, halo, acyl, ester, carboxylic acid, formyl, nitrile, sulfonic acid, aryl groups or linear or branched alkyl having 1-15C, possibly functionalized with halogens or joined to each other in order to form one or more cycles condensed with the phenyl ring, and nitro groups;R4, R5=electro-donating group such as H, OH, ether, amine, aryl or linear or branched 1-15C alkyl groups.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The catalysts are prepared from metal complexes formed from salts of manganese, molybdenum, iron, cobalt, nickel, palladium, iridium and their binary, tertiary and quaternary combinations and templating polymers obtained by the condensation of a 4-(1-((phenyl-2,4-disubstituted)-hydrazine)-alkyl)-benzene-1,3-diol with phenol or 3,5 disubstituted phenol and formaldehyde or paraformaldehyde in the presence of a basic or acidic catalyst in water/alcohol mixtures at 20-150degreesC and have an eventual molecular weight of 1000-50000. The polymers are of formula (C).y=2-120;x=1-2;n=1-3.
