PORTABLE HYDROGEN GENERATOR DEVICE WITH POTENTIAL OF POWER GENERATION FROM HUMIDITY

Publication No.: WO2023281291A1 12/01/2023

Applicant:

ABAZARI SAEID [IR]

Absstract of: WO2023281291A1

This hydrogen generator utilizes distilled water to provide the needed distilled water, as the water supplied from the air humidity needs no treatment, eliminates the energy production process, and alleviates the device energy requirement. On the other side, within the electrolysis system, the number of oxygen-generating steel plates characterized with the positive pole is lower than those steel plates with negative pole and hence hydrogen gas generation is much more than oxygen gas. As this approach does not generate excess oxygen gas, the electricity consumption of the device is lowered. Such two major pros of the device make less power consumption and hence it may be utilized as a green generator.
