i will use the above described circuit in electrolysing or electrochemical reaction .
1-if you have chemical back ground i will electrolyse aqueous acidic solution in which i dont need the hydrogen to evolve with me ok!!!! thats first
2-this would achieved using carbon electrode (internal graphite in A battery )
3- this electrode would be of high hydrogen over potential to prevent the evoultion of hydrogen
4- the best conditions to aciece the abone conditions are as follows
voltage v current density Amp/Cm2 efficiency of reaction (%)
1.5 0.017 60
1.6 0.024 61
1.7 0.055 63
1.8 0.076 67
1.9 0.147 80
2.0 0.247 61
2.1 0.846 23
2.2 1.456 15
from the above data you can see how i really need it precise as the efficiency decrease from 80 to 61 by increasing the voltage by 0.1 v !!!!!!!!!
but if it went like what you noticified 0.05 increments so it may work i think !!!!!
for one electrode the surface area approximately = 14.326 cm2This should work for what you need. If you can give me the exact electrode sizes, then I can verify that this circuit will be able to handle the current load.
Good luck.
ok sir
but if i dont need voltage below 1.2 V what i will eliminate
This is awkward, but...
