摘要：

The method of Nafion(R) impregnation of the electrode to create an improved three-dimensional reaction zone at the electrode-proton exchange membrane interface was used to develop an electrolyzer capable of attaining higher energy efficiencies. The electrochemical characteristics of the cell, operating with a Ru-Ir-Ta oxide anode and a Pt-black cathode were determined by cyclic voltammetry, steady-state potential vs current density and lifetime studies. At 85-degrees-C and a current density of 1 A cm-2, the cell potential was 1.85 V, the value of which was almost constant for a period of over 1000 h. The flux of water across the membrane was measured. As a complement, operation of the same electrochemical cell in fuel cell mode was demonstrated.
