Hi ResinRat,

Thanks for that, I've attached the drawing in Google Sketchup format.

I need to think the zincates through, I understand the way you determined that was what they were... could there be another explanation? Is there a definitive answer why an Al screw run into the Zn electrode would cause a difference in the reaction? By this same measure, wouldn't the copper wire be a part of the reaction as well?

As for the fuel cells you guys are buying... if you pipe the pure O2 generated into the cell as well and stopped using Air you could double the current the cell could produce and be able to run Alkali Fuel cells (http://en.wikipedia.org/wiki/Alkaline_fuel_cell). You can build them as described here for very little investment (http://www.youtube.com/watch?v=-cQg0Ur9Cko&NR=1). If they were good enough for Nasa, why not us? As long as NO Carbon Dioxide enters the cell... it's about as reliable as it gets and can be close to 70% efficient! The interesting thing is... These cells would probably run with the same Alkali mix we are using in the generators now. This means that if any of the fluid enters the cell... it would probably be a good thing from time to time as it would replenish the electrolyte.

I have been playing with fuel cell designs for awile now and I figure if you made that cell... in a 8" by 8" design, you would be getting ideally about 0.7 Volts at 4 Amps. You will not get a single traditional cell in any system to give you more than a Volt. Thats why we have fuel cell stacks.

What would happen if we built an 8" x 8" cell... but instead of two single mesh's we had eight mesh's wired to simulate a stack of 8 cells? That would give you a single enclosure and electrolyte cell that produced 2.8 Volts at 1 Amp! Now if we built a single similar cell that was 1' by 1'... With 18 mesh plates wired in series. We would have a single cell that could produce 6.3 Volts at 1 Amp.

Yes the electrolyte would short everything out unless you used an interesting gasket or silicone to seal the individual cells and keep them from shorting each other... If not... we could just build a traditional Cell stack...

That could easily drive a microcontroller that could in turn handle the regeneration swapping and be able to run a pulsed current through a voltage multiplier (http://en.wikipedia.org/wiki/Voltage_multiplier) giving us 12 Volts at 0.5A!

Now consider taking this and building a traditional Cell Stack with these all wired in Parallel? A stack of four could give us 12V at 2A continuously charging 12V batteries... then add an inverter 

Cheers,

Chris

Hi Chris, I reposted you questions and my answers are in blue.

I need to think the zincates through, I understand the way you determined that was what they were... could there be another explanation? Is there a definitive answer why an Al screw run into the Zn electrode would cause a difference in the reaction? By this same measure, wouldn't the copper wire be a part of the reaction as well? You are correct about the copper wire. It all has to do with an element's tendency to want to donate electrons. This applies to Standard Reduction Potentials in the half-reactions we are dealing with in a particular system. Here is a link to a listing of various Potentials:

http://wblrd.sk.ca/~chem30_dev/appendix/tables_charts/red_potentials.pdf

The lower an element is in the table, the greater tendency it has to donate electrons. Zinc is higher up in the table than aluminum, so aluminum has a greater tendency to transfer electrons to the zinc, thus causing the zinc to precipitate out. Unfortunately in our electrolyte solution the zinc is in the form of zincates (Zn(OH)₂)  so it will precipitate out as a zincate, not as pure zinc. This is why we need the reverse current applied in order to free up the oxygen and allow the zinc to replate as pure zinc.

Now look where copper is in the table (Cu). It is above zinc in the table so zinc actually has a greater tendency to dotate electrons to it than the other way around. That is why if we put the copper wire by itself into the solution it would not precipitate out the zinc, but the aluminum wire does precipitate out the zinc. I think this is my feeble attempt at the best way I can explain it.

As for the fuel cells you guys are buying... if you pipe the pure O2 generated into the cell as well and stopped using Air you could double the current the cell could produce and be able to run Alkali Fuel cells (http://en.wikipedia.org/wiki/Alkaline_fuel_cell). You can build them as described here for very little investment (http://www.youtube.com/watch?v=-cQg0Ur9Cko&NR=1). I posted this video in this thread in the past. Unfortunately, I couldn't obtain the platinate chemical. It is listed as hazardous in the United States, so only companies or corporations that qualify to handle hazardous chemicals can obtain it. I couldn't buy it myself (I tried) and the company I worked for said they would be liable if I was injured using it at home. So this was impractical for the average citizen to get. So without the chemical, I can't build the fuel cells.

Thanks for your efforts and drawings. Very nice job, but don't give up yet. Keep searching, you may find the answer that I missed.

Hi Mike,

My brother is in the process of welding the tungsten/carbide electrodes together. Once he is finished I will begin the final assembly of the remaining parts.

Patience is a virtue given only to the wise. That is why I am MORE anxious to get this going than the rest of you. (LOL)

Obviously I'm not a wise-guy. LOL

Hi RR2,

Thanks for the explanations! I'm still making my way through this thread and am still only at page 49

I read that you don't "HAVE" to use platinum as the core of a fuel cell and that Nickel also worked but wasn't as efficient and needed more surface area to work as well. i.e. you build a cell twice as large and you get the same results... and the same fuel consumption as the smaller platinized cell. I'd rather build a larger cell that I could one day "upgrade" to platinum... Have you tried talking to your local Jewelers store? They do platings all the time It'll cost you a little but you get what you pay for.

Keep up the good work!

Chris
