Want to build a fuel cell HHO, but do not know which type to choose? While most cells will generate some HHOs, there may be an intense difference in output from one to another, so it is important that the design is correct.
HHO is created by electrolysis: electricity is carried through water between two charged poles or electrodes. The substance and shape of the electrodes can vary, although they should be made of an inert metal, preferably stainless steel. Below are four basic electrode designs.
The type of electrode that is easiest to build — and one of the most popular — consists of two or more wires wrapped in a spiral around a support mechanism. Unfortunately, it is also less efficient, since a small metal (maybe several square inches) is actually exposed. The amount of HHO gas that can be generated directly refers to the surface area of the electrodes.
The second type of electrode is made of steel mesh, similar to the mesh you would use for screen doors or windows. The grid is cut to fit into the container and fit into various configurations. Each layer must be isolated from the others - if the layers are in contact with each other, they can cause a short circuit. This type of electrolyzer makes many bubbles, but is not very impressive in terms of the density of the produced HHO gas.
Lamellar designs are the most widely used and most effective. Because of their large surface area, plate electrodes have the highest energy conversion to hydrogen and oxygen, while at the same time losing very little energy in the form of heat. High-quality stainless steel plates are resistant to corrosion, so they are used in industry to produce a huge amount of gas.
Pipe designs are the second most effective for metal plates. The tubes can be placed in a Stanley Meyer ring or stacked concentrically, one on another. The problem with pipes is that their maximum usable area will be limited to the smallest tube. The tubes, along with the coils, also overheat.
These are the four main types of electrodes. There are also two different types of fuel cells: wet and dry. In a wet cell, the plate (or other type of electrode) is completely immersed in the electrolyte solution. In a dry chamber, the stack does not sink. Instead, the solution is placed in an external reservoir and under the action of gravity through the holes that have been drilled in the plates.
Both cell styles have good and bad design points. Recently, a third cell style was developed, which seemed to combine the best aspects of wet and dry cells. Generally speaking, in this hybrid type, the container container serves as a reservoir, but the electrolyte remains below the top of the plates.
As you can see, there is no final version of the HHO fuel cell, which means that it is difficult to understand which type to build. Using plans developed by experts and tested over and over again can certainly save a lot of time. The most important thing is to just get started and get amazing benefits than the HHO cell can provide.
