Current Draw vs. Gas Production
Does anyone know what the link is between cell current draw and gas production? We did some simple tests last week and noticed that as stirred in more baking soda or Epsom salt the current draw increased as did the gas production.
Do different electrolytes produce more gas per amp? Or is gas production a function of electrode orientation, size or spacing?
I guess the next step is to modify our setup to measure gas production. I've seen some videos on youtube that talk about liters of gas per watt to the cell. Is that the best way to gauge output?
Efficiency vs. Gas Production
There seems to be some confusion about the difference between Efficiency and Gas Production.
EFFICIENCY
This is all about maximizing gas production while at the same time minimizing the input power. Numerically, this can be stated as LITERS PER MINUTE PER WATT(L/M/W or LPM/W). The larger this value is the more efficient the electrolyzer is. In my mind, this is the most import aspect.
GAS PRODUCTION
This is all about getting as much gas output as possible. Numerically, this can be stated as LITERS PER MINUTE(L/M or LPM). The larger this value is the more gas you are getting from the electrolyzer. It is important that your gas production meets your demands. Also, gas production basically follows the current. This means more current will get you more gas production. Keep in mind that heat follows the current as well. Electrolyte(the material between the plates including water and chemicals) changes the resistance of the electrolyzer. Pure water is fairly resistive. Adding chemicals and/or heat will decrease the resistance and current/heat/gas production will increase.
