Selection of Electrolytic Cells

Flow rate of the electrolyte, change of concentration dming the process, operating temperature, pH of the electrolyte, etc. 

Electrolyte composition required for efficient operation (whether special additives are required for lowering the operating resistance) 

Cunent-canying capacity of the electrodes (depends on the conductivity and cross section) 

Graphite is a common electrode material due to good electrical conductivity and high thermal and corrosion resistance, but the threaded pieces and couplers are delicate and need to be carefully handled. 

Maximmn current carrying capacity expressed as Maximum Current Density
