if i was going to us a PWM to power my fuel cell threw chokes, i would measure the volts and amps before the circuit, not the chokes, then i would measure the amps and volts to and across the cell.

I`v just saw your last vid 41 on youtube.
You are putting in    40 volts, 7 amps (280 watts)
you are getting out  38 volts, 19 amps (722 watts)

722/280*100 = 258%
Is that right  ???

I've been researching and now started to put together my first cell following SM's work.

I would appreciate any comments based on your past experience or mistakes. Thanks!

Here's my Plan View. Working on Elevation View now.

Hello Flaghole;

I'm new to this forum and by no means an expert.

But,  for my first career I was a hydraulic pipe fitter for over 12 years.  In my opinion, the thin walled extruded acrylic tubing is not the way you want to go if you plan on pressurizing the cell. 

Acrylic is already considered a hard plastic, very fragile and loves to crack on you. 

If you must have a crystal clear cell, and want to go with acrylic, then I would recommend that you use CAST acrylic tube with a 1/4" wall thickness.  It's more expensive, but at least it will be able to handle some pressure.

You can also find clear schedule 40 and schedule 80 PVC pipe.  Polycarbonate (Lexan) is also another good alternative, but again it's expensive and difficult to glue.  Weld-On makes great products for gluing all kinds of plastics and plastics to metals.

well thats my two cents,

Your gap is to wide, Unless your cell is going to be 24" tall or more.  Try to get at least .065 wall thickness,  Or .095 if you can. You will get better production.

I got good production at .024", but now I use .065" cuz my tubes are longer.

How's the new 100amp alternator working out for you spike?
