TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The tertiary diamine is tetramethylenediamine, 1,4-diazabicyclo(2,2,2)-octane, N-methylimidazole, bipyridine and/or diimidazoline. The tertiary monoamine is triethanolamine, quinuclidine and/or quinuclidinol. The components (c1) and (d1) are replaced by or associated with organic polymer comprising at least two groups having polymerizable double bond, preferably located at the end of the organic polymer. The cathode is an air electrode.    TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The temperature of heating step (b) is 30-130 degrees C, preferably 50-80 degrees C, for 1-24 hours, preferably 6-16 hours. The reaction solution prepared in the step (a) further comprises tertiary monoamine. Preferred Components: The organic polymer bearing reactive halogen groups is homopolymers and copolymers having polyether backbone. The organic polymer bearing reactive halogen group is epichlorohydrin homopolymers and copolymers. The monomer having ethylenic unsaturation is a group formed by 1-10C alkyl acrylates and 1-10C alkyl methacrylates, 1-10C hydroxylalkyl acrylates and 1-10C hydroxylalkyl methacrylates, styrene and its derivatives, acrylates and methacrylates of polyethylene glycol, vinyl acetate, N-vinylpyrrolidone, acrylonitrile, (vinylbenzyl)tri-1-6C alkyl-ammonium chloride or bromide, tri(1-6C alkyl)-vinyloxycarbonylalkyl ammonium chloride or bromide, and/or allyloxycarbonyl (1-6C alkyl)-tri(1-6C alkyl) ammonium chloride or bromide. The crosslinking agent having at least two ethylenic unsaturation is divinylbenzene, ethylene glycol di(meth)acrylate, poly(ethylene oxide)glycol di(meth)acrylate, and bisphenol-A di(meth)acrylate. The IPN material or semi-IPN material extending in a portion of the network of the porous electrode having air penetrates the porous network on a depth of at most 5%, preferably at most 2% of the total depth of the air electrode. EXAMPLE - Ethanol solution (A) having an epichlorohydrin polymer (200 g/l) previously grafted with 12 wt.% of 1,4-diazabicyclo(2,2,2)octane was prepared. Hydroxyethyl methacrylate (0.9 g), ethylene glycol dimethacrylate (0.1 g) and azobisbutyronitrile (0.05 g) were dissolved in the solution (A) (4 ml). The solution was degassed under argon flow and stirred for 30 minutes at room temperature. The solution was then placed in a mold formed by two glass plates (5 cmx 5 cm) separated by a Teflon (RTM: Polytetrafluoroethylene) gasket 1 mm thick. The filled mold was placed in an oven at 60 degrees C for 16 hours to obtain anion exchange polymer having interpenetrating polymer network structure.
