The two‐fluid effects on the radial outflow of relativistic electron–positron plasma are considered. It is shown that for a sufficiently large Michel magnetization parameter σ ≫1 and multiplication parameter λ n n GJ ≫1, the one‐fluid MHD approximation remains correct in the whole region | E |<| B |. In the case when the longitudinal electric current is smaller than the Goldreich–Julian one, the acceleration of particles near the light surface | E |=| B | is determined. It is shown, as in the previously considered cylindrical geometry, that almost all the electromagnetic energy is transformed into the energy of particles in the narrow boundary layer Δ ϖ ϖ ∼ λ −1 .
