1/16th" spacer gaskets

[Cowboy]

I'm a radio repairman and I'm a firm believer in the 3/2 fix.  3 ft off the ground, drop it twice, and it's fixed.

  Today(Mon. 2/16) I'm pulling the cell and dismantling it to chase down the voltage drop I have with 1 plate.I'm also adding e-lyte and outlet fittings to the opposite endplate and increasing the fittings from 1 of each on one endplate to 2 of each on both end plates to increase e-lyte feed and outlet pressure.I'm also elongating the outlet holes at the top of the plates to allow for gas accumulation to hopefully reduce all the yakking of e-lyte the cell does since the 1/16" gasket refit.This should also help with maintaining e-lyte levels,a problem I've been having since the refit.
  I think once this is done I'll have even more output because of the 1 bum plate with less than 1 volt pulling it's weight like the rest that all have 2.25volts.

  Will post all results later this evening.

Ok... I gott'a Ask... what is Yakking ? your electrolyte is Yakking ? you mean  makeing like a Yakk and runnin all over the place ? or  curteling like Yakks Milk in a warm sun ?  or are you refureing to the cell is complaining to you about the way its been treeted ? Yakking on all the time and won't get any work done ?
 a bit more clarification would help those of us that ain't smart enough to read ur Mind !
or put 2 and 2 togather !
....
<GRIN>
( get the butterfly net ready boys cuz if its talking to him we got a live one !)
HAHAHAHAHAHA
(couldn't resist! sorry Hg2 but I just couldn't pass it up... with all that Yakking going on out there ! )
....
HAHAHAH

  Ok Bob here goes:Your last post makes me want to yack.

  Examples:puke,throwup,spitout and the one a lot of us have done after party's,weddings and mostly after bachelor parties,praying to the porcelain god.

 

[Bob]

Hummm so your Hydroxy cell is Puking all over the place, and you hope to stop it by elongating the holes.....
Man I'm glad you cleared that up for us ! ....had me really worried ! <GRIN>
.... but a Bubble pump Yakks all the time .... thats how it works.... thats normal !
don't worry about it buddy !  let it throw up , it won't hurt a thing !
HAHAHAHAHAHHAHA
....

  The big problem Bob is that on long trips it will do it until the cell is almost dry.This never happened before when I was using 3/16" gaskets and producing 3.5 LPM ,now the output is almost twice that.We'll see if the mods I'm doing will correct the problem(hopefully).

You've run into the same problem I had, what causes it is the gas and fluid is leaving the cell faster then it can recirculate, 1" inlet and outlet cured mine, but the volume in the resivour still rose up quite high when running.

[Bob]

Well SEE ! there ya go ! Randy has the cure fer ya !
...thanks Randy !
any luck on your Big Randy cell lately
...

  Thanks Randy for the idea,that was something I was also thinking of if the added inlets and outlets didn't work.
  So far it seems to have cured the problem for now but I won't know for sure until I take a long trip because that's when the cell would almost go dry.

  Ahhhh the joy of trial and (mostly)error.

  I'm still having issues with voltage drop on now several plates.I noticed it when checking plate voltage and the one I was checking at the time went from 2.32 volts down to under 1 volt.After letting the cell run and warm up I found 2 more doing the same thing.I think what's happening is the plates being so large(9"x9") and along with the new 1/16" gaskets that the plates are warping as the cell warms up,because the plate voltage on those pates is ok up until the cell warms up.
  The only thing I can think of to remedy the problem is to revert back to the original tero plans that show a small square of gasket material placed in the middle of the plates to prevent them from bowing when they get hot.
  So it looks like another remove and tear down(GRRRRRRR)to see if this might cure the problem.

[Bob]

Hg2:
Are you using real soft gasket meterial and squeezing them real tight ? if so that tightness
is probly bringing the plates very close togather indeed !  and the plates warping might cause a plate to short out against another plate...check continuity between the plates not the voltage... warm it up and turn it off and check for continuity between plates
if there is continuity, even a small amount something is amiss !
  If the plates were shorting out against each other two plates would act like 1 plate and your voltage would then show a corosponding change...instead of 2vdc each plate  2 plates would share that voltage and become 1vdc each... so it sounds like your on the right track
adding a piece of gasket meterial in the center of each plate should stop the warpage in its tracks !... unfortionately you have to dissameble the thing to add the gasket piece...
but think of it as assembly practice ! HAHAHAHAHHAHAHA

how thick are your 9"x9" plates ? 

...

  Bob my plates are 16 ga. thick and the neoprene gaskets are the same kind of good commercial grade I've been using for over a year only not this thin.The reason I tore it down last week was for the bum plates voltage and I did notice on those 2 plates that faced one another that there was what looked like black burn spots about 1/8" in diameter in the middle of the 2 plates and in the exact location on both plates.

  I guess like you said it'll require some more "Practice Assembly"along with a center spacer. HAHA.

[Bob]

YUP,Yup... thats the sign of a plate shorting out. so you did find it!
I would use 1/4" square or just a tad larger Smaller than 1/2" square for your center spacer
and it might be advisable to add a bit of adhesive ( rubber cement/silicone) to one side of that little thing so it cannot move on you.
...
that tells me to get thicker plating than 16guage ! because I don't want my cell plates to worp
and short out.... its that or add a "HG2-spacer" in there!....<GRIN>
 ...
 My plates will be .24 guage, 12"x12" and consist of 7 plates and hopefully fed with a minimum of 75 amps.
132.25 sqr in each plate with 1/2" gasket  times 7 plates =925.75 sqr inches.
0.0810 amps per square inch....to as much as 100 amps makes 0.1080 amps per sqr inch.
(75amps/925.75 and  100amps/925.75)
... this is calculating all the plate area however...but its what I am used to , and I know the "Randy cell" that worked so extremely well has 0.03api... so it should work even better than the "Randy cell" but probably generate 4 times the heat ! <GRIN>
but I am after LPM and I don't care about the heat, I'll deal with that when I come to it!
...
if I make the cell a "in a dip" type I'll have 144sqr.in. x 7 = 1,008sqr. in.
using the same amperage as before gives me 0.0744api for 75 amps and 0.0992api for 100amps
...as you can see either way it should STILL produce very well
...
this setup will require a new larger alternator and a cooling system for the cell and I am planning on both... but I am hoping to net 20LPM from just 1 cell like this , if I don't get it from one I will build another ! and run 2 in parallel like Scratch is doing.
...
..
.
THE BIG PROBLEM is ...can I draw that much amperage ?, or will the saturation of water by the electrolyte stop me from doing that.... and I think it will !
so my output will be limited to the saturation of water in a 28% KOH/water setup or Koolaid
and I don't think Koolaid will get me as many amps as the KOH will !
but time will tell.
...
thats my Plan and time is getting closer where I can start getting the parts.to make this monster !

  Yeah Bob I just hope the "HG SPACER" cures my "GD PROBLEM". LOL
