    摘要: Mixtures containing vinyl-containing phosphonic acid, polymer electrolyte membranes comprising polyvinylphosphonic acid and their use in fuel cells. The present invention relates to a proton-conducting polymer membrane based on polyvinylphosphonic acid obtainable by a process comprising the steps A) Mixing a polymer with vinyl-containing phosphonic acid, B) Forming a two-dimensional structure using the mixture according to step A) on a carrier, C) Polymerisation of the vinyl-containing phosphonic acid present in the two-dimensional structure according to step B). A membrane according to the invention may on account of its outstanding chemical and thermal properties be used in a wide range of applications and is particularly suitable as a polymer-electrolyte membrane (PEM) in so-called PEM fuel cells.

    摘要: A transport container especially suitable to be supported on a cart or trolley, and also suitable for use in an aircraft, if desired, is constructed as a parallelepiped. Two oppositely located doors are connected by hinges to a frame structure. The hinges form part of the frame structure and allow the doors to open through an angle of 270.degree.. Corner braces having mutually perpendicular tenons mate with tubular metal stock such as sectional rods to form the frame of the container. The metal rods have U-rails for the mounting of wall, floor, door, and cover plates. A door locking mechanism is located in a hollow chamber of a door member or stile. The locking mechanism includes an interconnection of a sliding bar and two lock bolts. The rotation of a door handle actuates the lock bolts which retract into the stile for opening the door.
