HODINFO is a collaborative think tank. We are an International group comprised of inventors, scientist, mechanics, tinkerers, fabricators, and out of the box thinkers. Our mission is to find innovative solutions to the problems that primarily limit the production and delivery of H2. As the world wakes up to the idea of using hydrogen it also becomes clear that immense infrastructure initiatives will be required to make it happen. If adequate solutions can be found to support HOD systems then the world can remove great and costly limitations on future applications. It is important to realize that the future is not just Hydrogen, it's Hydrogen-on-Demand.

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 ?

Started by Hans Peter GROTE. Last reply by don Aug 9, 2012. 10 Replies

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

Can we increase HHO Production and Efficiency, if we pressurise our Dry-Cell to 75 p.s.i ?

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

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

Hello , Nice Group, I want to draw your Attention to several things have 

1 Stan Meyer Circuits for Bench top unit wet cell Original Spec with Chokes Done

   www.irondmax.com forum  tell Dan invited you

2 Fuel Line Live Monitor to 3g along with Engine Vitals live and Cloud Management platform Done and Available. 

3 ECu to unlock the car full potential and android tablet tuning DONE

4 Quality Split gas Cell 24 4 amp runs 24 hrs Done connect to ECU. 

I am Looking to expand Country Dealer /resellers and Installer partner at this time

I invite professionals in Business to contact me directly to discuss.

This might help.

Do not misunderstand me.  I said there is no electron movement in electrolyte.  Current moves in three forms.  Electrons in wire/conductive solids or ions in electrolyte.  It is still current.  The electrons are forcing the the ion movement so you  can measure this with your amp meter.  The electrons do not jump off into the electrolyte so to speak.  I am not an electrician but I do understand the two basic types of current.  Now in plasma both electrons and ions move.  In a reactor the ions are moving both ways and if they collide they become neutral and of no value to us.

is useless debate

"The anode of an electrolytic cell is positive (cathode is negative), since the anode attracts anions from the solution. However, the anode of a galvanic cell is negatively charged, since the spontaneous oxidation at the anode is the source of the cell's electrons or negative charge. The cathode of a galvanic cell is its positive terminal. In both galvanic and electrolytic cells, oxidation takes place at the anode and electrons flow from the anode to the cathode."


Carter was right again: in the cell due the presence of ionic and not electric conductor we may have ions who may moves in both directions - depend on electrolyte.

Comment by Barry Holzsweig on March 29, 2012 at 9:26am

hmmmmmmm.... Carter..... please answer me this. If there is no current flowing in the cell, why is it we can measure amperage on the positive and negative terminals of the cell?

Comment by Carter on March 29, 2012 at 9:01am

Just to make one thing clear here.  There is no electron movement in the electrolyte.  Ions are moving.  They are being pushed and pulled by the anode and cathode.  That means they the Ions are moving both ways. 

Comment by Barry Holzsweig on March 29, 2012 at 8:29am


Let me see if I understand what you are saying. Sometimes the written words do not convey full thoughts.

If I understand you correctly, you agree that current flows from the negative terminal to the positive terminal.  Now, are you saying that once the current reaches the negative terminal on our cell it somehow stops and that current from the positive terminal reverses course and flows to the negative terminal? That's what I'm understanding you to say from your last remark.

Comment by moldoveanu.marius on March 28, 2012 at 10:47pm


Polarity on battery is as you said: from negative to positive.

On electrolytic cell electrons arrive on positive pole (anode) and flow to ground ( cathode).

I understand now where your confusion come from: the cell was designed by someone else,,ask him! Is a fine engineer for sure! Nice design! 

If your team are interested we may exchange some information's and eventually you may give a try on my electrolyte formula or even some of my other components. Take a look to my page..I may have one of the best solutions for a fuel saver.

Comment by Barry Holzsweig on March 28, 2012 at 2:53pm

I have to give credit. The cell design is not mine. That cell was designed by Ed Grimm a one time NASA shuttle technician and meticulous designer!

Comment by Barry Holzsweig on March 28, 2012 at 2:49pm

Uhhhh... check your electrical theory. DC current flows from negative to positive! Don't believe me, google it up!
