Dry HHO cells are in fact an improvement in construction compared to the wet type of HHO cells. The end result of hydroxyl gas is the same in both types - differential ratios on the electrolyte reservoir and the displacement of the plate of electrodes.
The design of the wet cell has positive and negative electrode plates completely immersed in an electrolyte solution consisting of water and a catalyst.
Disadvantages of wet HHO design :
- More heat is generated through the cells.
- More current required (current strength)
- Positive electrodes (anodes) will corrode more due to the effect of oxygen on the metal surface (corrosion).
All these shortcomings are translated into the technical word. "Inefficiency".
More heat is released because the full volume of electrolyte solution is subjected to current for the electrolysis process. This additional current generates more heat, which eventually becomes steam; that steam is collected and replaces the volume of hydrogen gas.
The second drawback is the increase in current for the full volume of electrolyte in the tank for the implementation of the electrolysis process. The more current is removed from the car's charging system, the more fuel is lost! This is exactly the opposite of what the HHO generator should achieve.
The third disadvantage is that the anode plates that collect oxygen have a total surface area immersed in the cells, and the oxygen collected on these plates of each cell will form oxidation, which means that they will always go beyond their limits. and should be replaced.
Dry HHO cell design
The dry cell design of the HHO can be viewed as a cell for each cell. The best way to describe this in words is to present a square plate with a circle approximately equal to the width of the square. This circle is a closed chamber in which the electrolysis process takes place. This is the first advantage over the wet type.
Each cell plate, which represents the anode and cathode (electrodes), is sealed with a waterproof gasket or rubber sealing ring. The electrical connections are connected to the outer perimeter of each plate, which means that the connections remain clean and dry. These plates are bolted together with a dry perimeter using nylon washers to prevent polarity shortages.
The electrolyte is supplied by gravity or with an additional pump from an external tank (reservoir), which can be placed anywhere in the engine compartment. If the pump is not used, it should be placed higher than the HHO cell system.
Benefits of Dry HHO Cells
- Smaller current implementation for each cell is necessary due to the volume size of the electrolyte in the closed chamber.
- More subtle and compact in design, which is the main advantage of modern cars, which have very compact engine compartments
- Less frequent maintenance required for all dry HHO cell system
- Less corrosion occurs on the anode plates due to the limited volume of electrolyte solution per second.
- Less current means less heat, which can turn into steam inefficiency.
Dry HHO cell deficiencies
- The entire dry HHO cell must be completely dismantled for cleaning and maintenance, such as replacing the gasket seals of each cell, which leads to an increase in time compared to the maintenance of wet HHO cells
- Plates should be more accurate in hole sizes for maximum efficiency.
- It is a bit more expensive to produce compared to the wet type of construction.
The dry construction of the HHO cells was somewhat different from the various experimenters who had completed their own research and development. Some of them produce high-quality kits and are produced on a small-scale level.
In general, the best performer should be selected when making a decision to purchase a complete set, which consists of the smallest current withdrawal per equivalent of a liter of HHO gas (hydroxygas) for every 1 liter of engine power.
This ensures that you do not process HHO-gas, which is excessive for engine power with minimal current withdrawal. Excessive current drainage not only generates additional heat, but must also be backed up by an engine charging system using more revolutions per minute - which is the opposite principle of this fuel economy in the first place.
