Photoelectrochemical Systems for Hydrogen Evolution Using Ion-Conducting Membranes

A ceramic Li conducting membrane which consist from Li0.56La0.33TiO3 and an ion-conducting membrane MF4-SK (Nafion type) have been investigated in solutions with different pH values. It was found that the MF4-SK and LiLaTiO3 membranes work effectively in a photoelectrochemical system for the hydroge...

Summary:A ceramic Li conducting membrane which consist from Li0.56La0.33TiO3 and an ion-conducting membrane MF4-SK (Nafion type) have been investigated in solutions with different pH values. It was found that the MF4-SK and LiLaTiO3 membranes work effectively in a photoelectrochemical system for the hydrogen evolution. Is shown the fundamental possibility of creating an electrochemical cell with a membrane based on lanthanum-lithium titanates (LiLaTiO3). By using ceramic membrane pH in the cathode chamber of the cell were stable for 2-3 months. The ceramic membrane has an advantage over MF4-SK at a low current density and subject to a decrease in its resistivity (an increase in the area and a decrease in its thickness) to increase the current.
