Designing a cell requires consideration of many things!

One of the first things is working surface area.

This is important as it defines many of the other aspects of your cells performance and design.

One such area of performance is water contamination, which is influenced by the following factors.

• Current Density (The amount of Amps per square area of your cell)
• Voltage or Over Voltage (Usually leading to the above)
• Material (Stainless Steel 316L) offering a relatively low cost alternative (L) = Low Carbon
• Water Quality, that type and level of minerals within the water.

Provided for you here is a Current Density Calculator, type in your specifics to gauge it’s performance characteristics.
