yeh,
The strange thing is, that if you use 5volt, the amps are like 10 amps for a specific cell.
As soon as you put 10 Volts on the same cell, the amps will rise as well....to like 15 amps.
The formula p=u*I and U=I*R are fixed.
When you use plain tapwater and put different voltages on your cell, you will see different resistance numbers.
With stuff like KOH the numbers will be a bit different.
If the law of fysics is right and that every volt over 2Volts is turning into heat, then you cell must be very simple.
2Volts on the earlier mentioned cell pulls like 5 amps. (just an example...dudes
)
And you want to get a cell that pull 40 amps, then you have 2 options.
1. add like 8 till 9 cells in parallel/ The result will be that the overall resistance will drop drastically. That way it is able to pull the amps.
2. Because there is a limit on how low you can go with resistance, because you reach very quickly the deadshort condition, you may choose to use
the split option. That means that you use 2 power supplys in stead of 1. So you drive 4 cells on each powersupply. They are all in the same wfc. Thats oke.
As my low power test shows, you can get pretty nice production with a relativly high resistance (9.3Vp / 0.55 amps = 16.7 ohms!
Voltage is providing the road for conductance. It is lining up the watermolecules till a certain level. That why higher volts brings higher amps.!
I assume that the 2V level is the lowest level of conductance......
