is this normal?
Hi, I have a 4"x4" 11 plate dry cell(-nnnn+nnnn-) And a pwm hooked into it. I have a gallon tank with the right amount of koh installed. The cell is warmed up and the pwm dial turned down(all the way to the left). Now I am thinking that as I turn the dial(increasing it to the right) that the amps will go up. Well it will go up to about 11 amps max. The flow is all right threw my bubbler. So I turn the dial more and the amp draw decreases? I did this and noticed that the flow threw the cell at 11 amps the plate's were flooded and as the amp draw lowered the plates were only half flooded but bubbled more. Why and how can I get more lpm and keep the amps increasing. Tried to get it to say like 18 amps and see if I can get more lpm and it wont even get close to that. Even with more koh. Am i doing something wrong?Thanks for any help. Dave

I bought it on line from gasmaker. It looks like 1/8 spacing.

1/8 is good, that's becoming the gold standard for spacing.At 1/8 it won't pull many amp, but gives good production. A 4x4 is not going to make a lot of gas probably about 1/3 lpm. Does your cell have a refill line.You stated your cell water line lowered as you ran the cell. I'm thinking eather it doesn't have a refill line or its not high enought.Is their a web site we can see your cell.

HHOdave I looked at your cell,I think what your getting is normal.With the O-ring design you don't have a large working area and if you subtract for the fill hole,that's a little more than haft way the area is less. It reminds me of a fishing lure that design more to catch fishermen than fish. I don't mean to be rude but you'll need a bigger cell.
