Micelle diffusion coefficient and diffusion activation energy of SDS/BA/H2O system are determined by electrochemical methods without any probe. The results show that L1 area is not a single O/W microemulsion, it consists of two small regions-O/W microemulsion and oil-water bicontinuous microemulsion,. The microemulsion exists in liquid drop in O/W microemulsion and in net-structure in oil-water bicontinuous microemulsion. The diffusion property is better and diffusion activation energy smaller in the former than in the latter.
