Abstract: The invention relates to the field of electrochemical cells and fuel cells, more specifically to polymer-electrolyte-membrane (PEM) fuel cells and describes a process for the manufacture of membrane-electrode-assemblies (MEAs) containing five layers. The five-layer MEA is assembled together by means of a lamination process involving an adhesive component. The anode gas diffusion layer, the catalyst-coated membrane and the cathode gas diffusion layer are combined together by a low temperature / low pressure lamination process. Handling of the MEAs and assembly of the products into PEMFC and DMFC stacks is simplified. Less damage and perforation of the catalyst-coated membrane occurs and thus the performance of the five-layer MEAs is significantly improved. <IMAGE>

Abstract: This invention is directed to an improved zinc containing metallic coated ferrous product, particularly sheet and strip, which is resistant to intergranular penetration by zinc and embrittlement of the ferrous base. Use of such zinc containing metallic coated ferrous product in elevated-temperature service, such as found with certain appliances and automotive exhaust components, is enhanced by the coated products of this invention. The resistance to embrittlement of the zinc containing metallic coated ferrous base, when subjected to elevated service temperatures, is achieved by the use of a high-phosphorus containing steel base. For a plain content steel base, a phosphorus content of at least 0.020% by weight, preferably at least 0.030%, and more preferably at least 0.039% was found sufficient to render such zinc-alloy coated ferrous base resistant to embrittlement by zinc. By use of such high phosphorus ferrous base, for the reception of a zinc containing alloy coating, an improved metallic coated ferrous product has been found which resists intergranular penetration by zinc and embrittlement of the ferrous base. Such coated product has extended service life at temperatures above about 450 DEG  F. (232 DEG  C.) and when restored to room temperature possesses a high degree of ductility.

Abstract: Bolt anchored by impact for insertion in undercut drilled holes in masonry are known, which have an expanding body supported on the base of the drilled hole, onto which an expanding sleeve can be driven. These conventional bolts anchored by impact cannot be used in drilled holes which are not undercut, at least in relatively hard masonry. In order to provide a bolt anchored by impact which can be inserted in both undercut drilled holes as well as drilled holes without an undercut, in a positively locking manner, there is provided on the shank end of the bolt anchored by impact a plate with a cut-out whose side limbs can be spread in a V-shape by driving in an expanding body. The narrow edges of the plate can in this case bury themselves in the wall of the drilled hole and produce a positively locking connection to the masonry. <IMAGE>
