Hydrogen Permeation in Oxide Ceramic Membranes

Proton-conducting materials [38-47], analogous to oxygen conductors but with stationary oxygen anions, can show mixed protonic-electronic conductivity, without considerable oxygen transport in hydrogen or water atmospheres [40,41], These materials have not been widely studied in comparison 

The Physical Chemistry of Materials Energy and Environmental Applications 

To get an explicit solution of Equation 10.9, by integration, it is necessary to make some assumptions [39], In this regard, if the membrane material shows a high electronic conduction
