ADVANCED ALKALINE WATER ELECTROLYSIS USING INORGANIC MEMBRANE ELECTROLYTE (IME) TECHNOLOGY
The Belgian Hydrogen Research Programme, aiming at the development of a new concept in advanced alkaline water electrolysis has resulted in demonstration projects with prototype electrolyser units. The new concept, named I.M.E.-Technology (inorganic- membrane-electrolyte) produces hydrogen under pressure (0.5 - 4.0 MPa) at current densities up to 12.500 Am**-2 and temperatures not exceeding 120 degrees C. Electrocatalysts based on non-noble metals (nickel- sulphide at the cathode and a spinel oxide based on cobalt at the anode) are deposited on perforated nickel plates. These electrodes are pressed against an inorganic ion- exchanger membrane based on polyantimonic acid. Circular cells (surface area up to 0.2 m**2) are assembled in a filter-press-type manner. Prototype electrolysers, having an hydrogen production rate from 2.5 Nm**3 h**-1 to 25 Nm**3 h**-1 have been constructed and are tested.
