Abstract: Landolt and Ibls hypothesis on the model of anode diffusion layer is analyzed and two main ways of oxidation with respect to hypochlorite diffusing to the anode surface are considered. According to the analysis Jaksics mathematical model of current efficiency related to the anode diffusion layer is modified with an electrolytically characteristic parameter. The running fluid near the surface of gas-evolving electrode at a lower velocity is suggested to be in a turbulent pattern. A relationship between flow velocity, current density and thickness of diffusion layer is deduced. The influence of velocity and current density on current efficiency in the chlorate cell process is established by combining with the modified Jaksics model. The phenomenon of current efficiency with the increase of chlorate concentration is investigated with respect to activity, viscosity and chemical bond.
