evaluation of the zirfon Separator for use in alkaline water electrolysis and ni h2 batteries
International Journal of Hydrogen Energy, 1998Co-Authors: Ph. Vermeiren, W. Adriansens, J. P. Moreels, R. LeysenAbstract:Abstract Zirfon ® is a porous composite Separator Material composed of a polysulfone matrix and ZrO 2 which is present as a powder. The manufacturing is based on the film-casting technique. The Separator is very stable in concentrated KOH solutions at elevated temperatures. Even with a high loading of ZrO 2 it is possible to produce very flexible Separators with attractive mechanical properties. The main challenge for this Zirfon ® Material is to replace the asbestos diaphragms which are presently used in industrial alkaline water electrolysis. Different companies are already testing this Separator. Excellent results have been obtained. Another field of interest is related to the use of such a Separator in Ni-H 2 batteries both for earth and space applications.

Porosity in composite zirfon® membranes
Journal of Porous Materials, 1996Co-Authors: Ph. Vermeiren, J. P. Moreels, R. LeysenAbstract:The composite Zirfon® membranes are made of a polysulfone network and zirconium oxide as an inorganic filler. These composite membranes are actually being used for a variety of ultrafiltration purposes and as Separator Material in different types of electrochemical cells.

Porosity in composite zirfon® membranes
Journal of Porous Materials, 1996Co-Authors: Ph. Vermeiren, J. P. Moreels, R. LeysenAbstract:The composite Zirfon® membranes are made of a polysulfone network and zirconium oxide as an inorganic filler. These composite membranes are actually being used for a variety of ultrafiltration purposes and as Separator Material in different types of electrochemical cells. The main techniques which have been used for the characterization of the porous structure of these membranes are mercury intrusion porosimetry, scanning electron microscopy (SEM) and gas adsorption. As a major result it has been observed that the amount of ZrO_2 which is present in the membrane plays a dominant role: the structure of a composite Zirfon© membrane is completely different from the structure of a pure polysulfone membrane. The membrane becomes denser with increasing amounts of ZrO_2. There is also a strong indication that ink-bottle shaped pores are present and that their volume reduces with increasing amounts of ZrO_2.

mcm 41 as a new Separator Material for electrochemical cell application in zinc air system
Journal of Membrane Science, 2011Co-Authors: Hens Saputra, Raihan Othman, Agus Geter Edy Sutjipto, Riza MuhidaAbstract:Abstract The efficacy of nanoporous inorganic MCM-41 membrane as a new Separator Material for electrochemical cell has been investigated. The hexagonally ordered, narrow pore structure of MCM-41 membrane serves as ion exchange channels between the anolyte and catholyte of an electrochemical cell. Besides, it also acts as the electrolyte matrix or reservoir due to the hydrophilic nature of the as-synthesized MCM-41 and along with the high surface area and pore volume density characteristics. MCM-41 membrane has been employed as Separator in zinc–air electrochemical system. MCM-41 was synthesized on the zinc substrate by dip-coating method and its thickness was ca. 5 μm. The Zn/MCM-41/air cell was able to produce a maximum power density of 32 mW cm −2 and possessed a volumetric energy density of 300 Wh l −1 , which are considered comparable to the published product datasheet of commercial zinc–air button cells of equivalent size.
