Abstract
Anion-exchange membranes are useful for electro-membrane processes such as electrodialysis (water desalination, separation of inorganics from organic molecules, separation of specific inorganic ion, etc.), in-situ ion-exchange and ion substitution, electro-deionization for producing ultrapure water, polymer electrolyte membrane for alkaline fuel cell and electrolysis applications. The present invention discloses an acid and base resistant fluorinated hydrocarbon based anion-exchange membrane and its method of preparation thereof. In the first step co-polymerization is carried out between N-isopropylacrylamide and 1-vinylimidazole. In the second step, obtained inter-polymer of isopropylacrylamide-co-vinylimidazole co-polymer is mixed with poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) (IA-co-VI/PVDF-co-HFP), which is used for casting membrane film of desired thickness. The obtained casted membrane thin film is quaternized in methyl iodide solution.

Abstract
The present invention discloses a method for thermochemical production of hydrogen and oxygen from water by a low temperature, multi-step, closed, cyclic copper-chlorine (Cu-CI) process involving the reactions of copper and chlorine compounds. A method for production of hydrogen via Cu-CI thermochemical cycle consists of four thermal reactions and one electrochemical reaction and one unit operation. The cycle involves six steps: (1) hydrogen production step; (2) copper production step; (3) drying step; (4) hydrogen chloride production step; (5) decomposition step; (6) oxygen production step. The net reaction of the sequential process is the decomposition of water into hydrogen and oxygen. The methods for production of copper oxide which comprises contacting copper chloride particles with superheated steam and production of oxygen comprises reaction of copper oxide with dry chlorine as a part of hydrogen production by thermochemical Copper-Chlorine (Cu-CI) cycle. The reactions are performed in a flow through type quartz reactor as fixed bed type at high temperature and atmospheric pressure.

The electrolysis of cuprous chloride was carried out in the electrochemical cell. The particle size, current density, cathodic current efficiency, conversion of cuprous chloride and yield of copper formed depends strongly on current flow, heat transfer and mass transfer operation. The current flow, heat transfer and mass transfer are depends on surface area ratio of anode to cathode, distance between electrodes, concentration of HC1, applied voltage, flow rate of electrolyte, CuCl concentration and reaction temperature. The electrolysis of cuprous chloride as a part of Cu-Cl thermochemical cycle for hydrogen production is experimentally demonstrated in proof-of-concept work.
