We study a transport in composite system where the subdiffusive solvent (as for example gel) is separated by a thin membrane from the region where normal diffusion occurs. The solutions of the diffusion equation with fractional derivative are found in the system of interest. We also discuss the dependence of mean square displacement \sigma 2 on time in long-time approximation.
