    摘要: An electrolyte membrane with a backsheet is sent out from an electrolyte membrane unwinding roller, and is separated with its second side sucked on a suction roller by a first press roller. While the electrolyte membrane from which the backsheet has been separated is transported with the electrolyte membrane sucked and supported on the suction roller, an electrode ink is applied to a first side of the electrolyte membrane to form an electrode ink layer, which is dried by blowing hot air thereto to form a catalyst layer. Thereafter, in a state in which the outer surface of a second press roller disposed close to the suction roller is in contact with and supported on the first side of the electrolyte membrane, a support film is pressed against the second side of the electrolyte membrane by a third press roller and attached thereto to manufacture a catalyst-coated membrane.

    摘要: The invention relates to a method of manufacturing a membrane (1) from a blank (39) by a cure, which membrane comprises two rubber layers (40, 41) and a fabric-formed reinforcement layer (19), positioned between said rubber layers. In order to counteract and prevent respectively undesirable displacements of the reinforcement layer (19) membrane sections, which are movable in an application position, are manufactured according to the invention having a form, which deviates from the application form, and/or are exposed to stretching during the cure in order to within the membrane section bring about a displacement of said reinforcement layer (19) across a portion of at least one of the rubber layers (40, 41) and consequently a position, which deviates from the blank building up during the cure. The invention also relates to a membrane, manufactured according to this method as well as a mold tool designed to carry out the method and the manufacture of the membrane respectively.

    摘要: A hollow fiber membrane module and its method of manufacture are disclosed wherein the module is fabricated utilizing superior hollow fiber materials, namely high molecular weight (i.e. molecular weight>500,000 Daltons) polymers. In a preferred embodiment, the hollow fibers are fabricated from ultra-high molecular weight polyethylene (UPE). An array of UPE hollow fiber membranes is contacted with an extrusion of molten thermoplastic polymer at a contact temperature which is higher than the UPE membrane polymer. This high temperature application of sealing polymer does not collapse or otherwise deform the lumen of the hollow fiber, while assuring that the polymer can thus be applied with sufficiently low viscosity to provide adequate penetration around the individual fibers of the array to form an integral seal thereabout.
