Reagent Flux and Applied Current

A dimensionless current, comparing the applied electrical current to the current necessary to entirely convert the reagent flux, can be defined  

A single-pass high-conversion electrochemical cell should ideally operate at a dimensionless current close to unity, permitting high yields to be obtained at high current efficiencies. Dimensionless currents higher than unity are not desirable in principle as they are always associated with current efficiencies lower than unity. Furthermore, if the secondary reactions involve the desired product, dimensionless currents higher than unity lead to a rapid decrease in the material yield.
