Résumé

Two types of diaphragms for alkaline water electrolysers have been prepared. Their porosity, mechanical properties and electrical conductivity have been studied as a function of different methods of manufacture, with the aim of finding conditions leading to a low ohmic resistance of the diaphragm. The first type of diaphragm was prepared using inorganic oxides and hydroxides, bonded with PTFE, and sintered at 360 degrees C. The second type was made from a polysulphone bonding agent mixed with inorganic oxides. Endurance tests were performed in an electrolytic cell at 160 degrees C in 40% KOH solution for the PTFE bonded diaphragm. For diaphragms bonded with polysulphone, testing was carried out at 110 degrees C in 30% KOH.
