Plates: Made of 304 or 316L stainless steel in general. The plate Cells work very good. Sometimes even better with Pulse Width Modulation (PWM). The size of the plates, the thickness and distance between the plates is very important to make it most efficient. Although most plate-setups are vertical. Horizontal flat round plates are likely the best. Recommended.
The latest plates design in HHO Cells. PWM sometimes prevents the HHO cell from overheating.

Bolts: some very cheap designs use stainless steel bolts as electrodes. Not recommended. Will get hot quickly .
Wires: A few designs are using thin wired electrodes. Low volume gas production. Not recommended
Tubes: A good design are tubes. Depending on the specific size, material and setup this design works very good. It will produce high quality HHO gas in general without the need for pulsed-power. The round tubes design are being produced on large scale at the and of WW2 to power British army vehicles. (look at history) . The unit in the picture below has been tested by Brownsgas.com. We found out that it produces a lot of gas, stays pretty cool and doesn't need any maintenance other than filling it up with distilled water. Recommended.
Helix: Depending on the non-corrosive grade of steel used this desing works reasonably good although they don't match the quality of the round tube or plates design. Note: Brownsgas.com tested the unit in the picture below (at the left). It got very hot and the gas production per watts was not good. The electrodes also got dirty. We think it is the material of the electrodes used. In general: not recommended.
The Helix ( at the right) is a non-corroding stainless steel electrode.

There exists different qualities in HHO gas, depending on generator design. So, not all generator designs do actually produce high quality of HHO gas. (quality depends on the mixture of Hydrogen and Oxygen).
Good quality Brown's Gas - HHO Gas over 95% pure is implosive. Everything below 95% is explosive (!)
If the quality of HHO gas is low there can be other gases than Hydrogen and Oxygen in the gas mix. Which can be dangerous or make the gas highly explosive. Good quality HHO gas is pure oxygen and hydrogen and is highly implosive. This gas first implodes and than explodes. (within a millisecond).
