Description

Hydrogen generator {HYDROGEN GENERATING DEVICE}

The present invention relates to a hydrogen generator, and more particularly, to a hydrogen generator for generating hydrogen by electrolyzing water.

A hydrogen generating device using electrolysis is a device in which electric energy is applied to water containing an electrolyte or the like, and oxygen gas is generated on the anode side and hydrogen gas is generated on the cathode side as water molecules are decomposed.

Various types of devices are developed and used as such a hydrogen generating device. In general, a case made of a pair is provided with an inlet and an outlet through which water is introduced and discharged, a positive electrode plate and a negative electrode plate are disposed in the case, and an ion film is disposed between the positive electrode plate and the negative electrode plate. In addition, as water passes through spaces formed on both sides of the case based on the ion film, the positive electrode plate, and the negative electrode plate, water molecules may be decomposed by electric energy to generate hydrogen and oxygen.

The conventional hydrogen generator as described above uses a case made of an insulator such as synthetic resin, and arranges an ion film, a positive plate, and a negative plate in close contact with the inside of the case made of the insulator.

At this time, in general, various studies have been conducted to extend the contact time between water and the ion film, the positive electrode plate, and the negative electrode plate in a hydrogen generator. Conventionally, a method of slowing the flow of water by forming a water channel inside a case so that water can proceed along a specific path, and complicating the path of water introduced into the case, has been used.

In the conventional hydrogen generator as described above, even if the flow rate of water is delayed by forming a path through which water flows in the case, the efficiency of generating hydrogen by decomposing water is improved because only the time when water contacts the positive and negative plates is controlled. There is a problem with limitations.
