HHO Dry Cell

HHO Dry Cell Described

“Dry Cell” is a common name for a particular design of HHO electrolyzer or now known as HHO generator. Originally called the common-duct-series-cell electrolyzer designed and patented by William Rhodes, Yull Brown and Ernest Spirig.
The name Dry cell some say was coined by Bob Boyce and can be a bit confusing.These hho electrolysis generators use electrolyte and water like any other electrolyze r. The properties below will help you to see why it is a better design than the average “wet cell” hho generator.

Other common types of HHO generators, called wet cells use a series of plates submerged directly into the electrolyte solution, size of plates and configuration vary greatly depending on the application. Large amounts of the electrical current is “leaked” at the edges of the plates as the electrolysis action takes place.This current is wasted energy and does nothing to increase HHO production and a lot to create UN-wanted heat. The longer the plates are submerged in the water bath without the water circulating the more heat builds up and has no where to go.

The dry cell is also a series of metal plates each plate is separated by gaskets, rubber or other material such as silicone are found to work quiet well, the electrolyte is confined inside those gaskets. This creates a series of individual “cells”. The edges of the plates, including all of the electrical connections are outside of the electrolyte bath. The water is supplied to the Dry Cell from a reservoir tank placed above it and gravity feed to the cell, some also use special pumps to circulate the water if the dry cell kit is installed where the water tank can not be located above the drycell for gravity feed. If the HHO Dry Cell is constructed correctly the water then recirculates back to the tank by a self pumping action created by the electrolysis process

A few images of hho cells that will help illustrate these differences in design:

You can see the gaskets between the edges of the plates in the dry cell picture. You can also see in this picture that the electrical connections to the plates are outside away from the electrolyte bath.

hho dry cell inside In order to get electrolyte in to the cell plates, and to let the gas get out, the cell plates have holes in them. A properly built hho dry cell has holes at the top of each plate, so that the HHO gas can pass from between the plates to the outer sides of the cell and be carried back to the reservoir tank along with water solution. There should also be holes at the bottom of each plate to allow the electrolyte to circulate. The upper fitting allows the HHO to get out of the cell, along with water recirculating and the lower fitting is for replenishing electrolyte.
HHO2u has perfected a 3 hole design – the 3rd hole has proved to give the dry cell a pumping action that hasn’t been match, this speeds up the recirculation of their cell and helps them run cooler for longer periods of time.

The “Dry Cell” is a very simple concept. There are still a great many variations in this design from one Dry cell kit to another. Number of power plates, number of neutral plates, how the plates
are powered, and how much voltage is applied from plate to plate, are just some of the variations.

But if they are considered dry cells they have the qualities described in here.

Remember the dry cell generator (electrolysis generator) is just part of a complete Dry Cell kit.
