Editorial: Revista de Chimie, vol 59 nr. 10, p.1140-1142, 2008.

Rezumat:

A novel electrochemical cell for the evaluation of the ionic conductivity in polymer conducting membranes is proposed. This cell has the advantages of being able to determine with high precision the membrane thickness during electrochemical impedance spectroscopy measurements. A conductivity factor is also proposed in order to classify various membranes with respect to their conductivity versus a reference membrane, namely Nafion® 117.
