✦ Synopsis

The mobilities of Na+, Cl-and OH-ions and water in Nation 120 membrane have been discussed. According to the frictional formalism they have been expressed in terms of friction coefficients describing single interactions between components of the system. The signiticant influence of the movement of water on mobilities of Nat and Cl-ions has been quantitatively shown. Due to a different transport mechanism of OH-ions their mobility is influenced to a smaller degree than other ions.

In order to prepare a free-standing polypyrrole hhn with high mechanical strength, Fe(II1) form or Cu(I1) form cation exchange membranes were immersed in an aqueous pyrrole solution. Polymerization speed of pyrrole in the Fe(II1) form membrane was faster than that in the Cu(I1) form membrane. A line
