Is Stainless Steel 316L the best Material to use as Electrodes ?

Started by Hans Peter GROTE. Last reply by Barry Holzsweig May 20, 2013. 1 Reply

How about use Nickel-Brass for Cathode and Hastelloy C2000 as Anode ?The electrical Conductivity of these Metalls is much better than SS 316.With this we could use a non-caustic Electrolyte like…Continue

How does the Thickness of the Electrode Plates affect the HHO Production ?

The internal electrical Resistance is reduces by increasing the thickness of the Electrode Plates.  This would also increase the Voltage between the Plates and improve the HHO Production !Continue

Why are Dry-Cells better for Hydrogen Production than Wet-Cells ?

Dry-Cell Construction is more compact and produces less heat.

@Barry

the electrons flow from positive pole ( anode ) to negative ( cathode ) in a electrolytic cell. The voltage is not equally divided if there are more than a number of plates ..Current density may be not be the same on all cells in equal plates design. Your design is way much clever!

@ Hans : i was wrong : the parallel config need 10-11 cells at 24 volts not 6-7 as I said. Carter is right. Is also right about the fact that 24 volts systems are usually long run vehicles. Stop-go vehicles need on neutral less or a heater. Some solutions were presented here.

Tips:  - sand blast the cathode and polish the anode side of neutrals to balance the surfaces.

       - to avoid overheating is good to use hot water when make the electrolyte mixture. Rise the temp to 60 C and add the base until reach the desired current value at average voltage that will "feed" the system. Will not exceed that limit  with dangerous values if  run longer time.

24 Volt systems are usually long running and even 25 - 7 running and once warmed up do not stop for long periods of time.  11 cell (10 N's)  with 2.1 to 2.2 volts per cell works the best in the testing I have done.  If it is a stop and start type engine where it does not have much time to warm up then you can go down an N.  Heat should never be an issue in a well designed reactor.  Ambient might be an issue in colder or hotter climates but then usually location of the reactor and reservoir with good insulation/ cooling solves most of these problems.  I have found in a dual reservoir system that running engine coolant after it comes out of the heater through the lower reservoir before going back into the engine/radiator keeps the electrolyte plenty warm enough and requires no additional pump etc.  This is an advantage in sub zero weather and only comes into play when the heater is on.

Regarding neutral plates...

H2 and O2 are produced when the water in the cell touches the positive or negative pole (plate). The neutral plates are induced with current flowing from the negative terminal (or plate as the case may be) to the positive terminal (plate). HHO is produced as the current flows through the water solution between the neutral plates on its way to the positive terminal (plate).

 

So, whether you use 12vdc or 24vdc, makes no difference. It's amperage you want to manage and you do that with size of the plates, how close together they are in the solution and the strength of the solution. With our systems, the highest amperage we draw on our cells for a 14 liter diesel engine is 15 amps. That's efficiency. And it's designed to withstand 60 PSI. We inject, 1.6lpm of HHO into a 14 liter diesel and attain a consistant 20+% increase in MPG on the highway. remember, it's supplemental hydrogen...  a little bit goes a long way.

Oh and you can also send output to a variety of LCD screen shields.  Essentially, you can build so much more than just a plain old constant current PWM.

Comment by Stephen on March 28, 2012 at 12:32pm

So essentially, this thing can take various 5v inputs such as many found under the hood of your favorite 1990+ automobile (e.g. MAP, MAF, and many more).  You write simple code to control the PWM outputs which could be a solenoid, pump, HHO generator or something else.  It's open source and super easy if you have any sort of programming skills.  Even if you don't, there are plenty of tutorials on the web as the source code is open.

@ Stephen:

Nice one that Arduino! :)

Comment by Stephen on March 28, 2012 at 12:29pm

Here's a link to Arduino: http://www.arduino.cc

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.

@ Stephen: what is Arduino?

@ Hans: 5 per each set in your configuration will provide best results with low electrolyte. Question 1.did you tried the electrolyte  formula I told you? 2. Did you get my emails? 3. have you checked the new comments I add to my page, I add some links there with gas production at various voltage and conditions. I can't use You Tube ..

Comment by Stephen on March 28, 2012 at 12:14pm

And to further my comment: if you had a temperature sensor, pump and solenoid you could use an Arduino and motor shield to keep the temperature just where you want it.  I think this temperature is approximately 130 degrees F/ 55 degrees C.
