I have build a double wet 6 serie cel, using 13 stainless steel plates 6"x6", 3mm gap, KOH, 12 volts from a power supply, zero current leak, no pwm,
I found that 6 cells is too much for 12 volts. I had to put loads of koh in to get the amps flowing. 6 cells might be better in a car, because that gives 13,5 to 14 volts. But with my 12 volts, it doesn't.
I changed the cell to double 5 cells. With 5 cells it works much better. With only a teaspoon of koh it pulls 15 amps. After a while, when it starts to heat up, it gets to 18 apms.
Now i am getting 1 LPM at 18 amps. But i was hoping to get 1 LPM at 10 amps.
Is 18 amps for 1 LPM the best i can get? What to do different to get more LPM's?
