This article outlines some history of and recent progress in perfluorinated membranes for polymer electrolyte fuel cells (PEFCs). The structure, properties, synthesis, degradation problems, technology for high temperature membranes, reinforcement technology, and characterization methods of perfluorosulfonic acid (PFSA) membranes are reviewed.

A novel cathode with a metal hydride and a Raney nickel electrocatalyst has been developed for highly durable low hydrogen overvoltage cathodes in chlor-alkali electrolysis cells. The cathode is made by composite-coating a Raney nickel alloy and a metal hydride on a cathode substrate. The cathode exhibits a low hydrogen overvoltage (ca 80 mV at 90°C, at 30 A dm 2in a 35 wt% NaOH), and has excellent stability under cell short-circuiting shutdowns as well as under normal operating conditions. The mechanism of the excellent stability under shutdown conditions has been discussed.

Abstract The study of a new alkaline type ion-exchange membrane water electrolysis, on the basis of AZEC, developed by Asahi Glass Co. Ltd. is described. AZEC is a membrane, Flemion DX, applied in conjunction with active electrodes, where the distance between the membrane and the electrode is maintained at zero, or nearly zero. Flemion DX is an organic and inorganic composite membrane, the surface of which is covered with porous inorganic nonelectrode layers. These layers make the membrane surface hydrophilic so gas bubbles hardly adhere, excluding problems caused by sticking of gas bubbles. In the laboratory AZEC cell, a cell voltage of about 1.7 V and a H2 purity of above 99.9% were achieved at 110°C, 70 A dm−2.
