ABSTRACT:
The invention concerns an electrolyzer power supply, especially for use in the industrial production of hydrogen. It is constituted by four sub-assemblies placed side-by-side in a filter-press type structure. These sub-assemblies each comprise electrodes coupled two by two, electrolytic compartments being defined between two groups of electrodes. One group of these electrodes, preferably half of them being made of a metal that has a rectifying effect on AC current, and preferably being aluminum, aluminum-zinc alloys, niobium or tantalum. The counter-electrodes are adapted to evolve oxygen. They are preferably iron, nickel or carbon. A generator providing an alternating current is connected between the end electrodes and between the second and third sub-assemblies. DC is taken from between the first and second and from between the third and fourth sub-assemblies.
