When you get the KOH, make it a 28% mix. By running 5 bipolar plates per stack, it will draw less amperage, put out more gas/less steam, and run cooler.
I personally run 6 bipolar's per stack. My new reactor is 6x9 with 14/2.
That's (-NNNNNN+NNNNNN-). With a 28%KOH E/lyte (roughly 2lbs. per 3/4gal.),
I'm getting 2.4LPN @ 26 amps. without steam with a 7.21MMW and only 0.24 current density (A/sq.in.).
The plates (after an hour) stay at about 120F & the gas is 70F.
