This invention relates to the field of hydrogen energy production and internal combustion engine power supply technology, specifically to an integrated power supply technology based on weak electric excitation and electron double recombining mechanism, which enables instantaneous hydrogen production upon water addition, simultaneous hydrogen storage, and direct power supply to the internal combustion engine. This technology belongs to the interdisciplinary field of new energy and power systems. Currently, hydrogen energy production, storage, and power supply technologies worldwide suffer from significant technological limitations. This invention abandons the traditional hydrogen production catalytic mechanism and innovatively employs a weak electric excitation + electron double recombining physical mechanism: using a weak electric field (low voltage, low current) as the excitation source, it acts on a graphene-based lithium-potassium composite medium with a slightly higher potassium content than lithium. Through a weak electric field, a double recombining reaction of electrons occurs within the medium, generating a polar intermediate. Hydrogen is directly produced by decomposing water without the need for high temperature, high pressure, or strong electricity, while simultaneously achieving synchronous in-situ hydrogen storage. The hydrogen can be directly supplied to the internal combustion engine for combustion, forming a complete closed-loop power supply system.
