The present invention relates to novel polyazoles, a proton-conducting polymer membrane based on these polyazoles and its use as polymer electrolyte membrane for producing membrane-electrode units for PEM-fuel cells, and also other shaped bodies comprising such polyazoles. In the method, an adhesive containing diphenylmethanediisocyanate an amount of less than percent by weight based on the whole amount the adhesive and having an elongation at fracture adhesive of 150\u20131,500 percent after complete curing is employed, and the blanc IC card sheet is cut when an elongation at fracture of the adhesive of 5\u2013500 percent prior to complete curing. The means of attaching tabs could be an interlocking mechanism such as dowel interlock feature in FIG. The ETLS servlet also operates on the computer network and is securely coupled to the primary server. At run time, a pageContext object is created containing a mapping of scripting variables to values. The apparatus and method include a reducing chamber that receives contaminated residual powder resulting from an additive manufacturing process and remove oxygen from the contaminated residual powder to produce reconditioned powder.
