Absstract of: WO2026197921A1
The invention relates to a synchronised multi-phase electronic system, a dissociation apparatus and a method for producing hydrogen and oxygen from water via the application of a composite electrical signal. The system includes a master synchronisation generator which coordinates an inductive phase that generates a pulsed signal, an inverter phase that produces a high-frequency alternating signal, and a low-amplitude resonant phase. A coupling stage combines these signals and applies them to a conductive aqueous medium to induce non-steady-state electrochemical conditions that promote molecular dissociation. The apparatus comprises tubular columns having reaction cartridges with thin, flexible plates, a recirculation and cooling unit, and a hydrogen storage tank with high- and low-pressure lines. The associated method allows the efficient generation of hydrogen and oxygen, using less energy than conventional electrolysis.
