20080287276 | PAPER SCORING SYSTEM - A scoring system uses a grooved roller and a variety of resilient annular scoring tools. The scoring tools have scoring features or blades of different profiles, and further have annular bases uniform in width to enable their interchangeable installation into one or more tool-retaining grooves formed into the roller. The bases are much larger than the scoring features to provide increased strength and durability, along with more stable mounting of the scoring tool. In one version, a single roller assembly is formed by removably securing processing sleeves and spacing sleeves on a common support member. | 11-20-2008 |

20090220834 | MEMBRANE-ELECTRODE ASSEMBLY HAVING A MULTICOMPONENT SEALING RIM - The invention relates to a membrane-electrode assembly having a multicomponent sealing rim, with the rim components being joined by means of two different joining methods. The rim construction of the membrane-electrode assembly comprises at least two materials (sealing material A and frame B) which are joined to one another both by adhesion and by physical locking. The frame B has at least one perforation through which the sealing material penetrates and establishes an intermeshing connection. Adhesive bonding methods, lamination processes and/or injection moulding processes are suitable for producing the multicomponent rim and the corresponding membrane-electrode assembly. The multicomponent rim construction has a high bond strength. The membrane-electrode assembly having a multicomponent rim is used in electrochemical devices such as fuel cells (PEMFCs, DMFCs, etc.), electrolysers or electrochemical sensors. | 09-03-2009 |
20110308726 | A Process for manufacturing a [[C]]catalyst-coated ionomer membrane with protective film layer - The present invention relates to the field of electrochemical cells and fuel cells, and more specifically to polymer-electrolyte-membrane fuel cells (PEMFC) and direct methanol fuel cells (DMFC). It is directed to catalyst-coated ionomer membranes (“CCMs”) and membrane-electrode-assemblies (“MEAs”) that contain one or more protective film layers for protection, sealing and better handling purposes. The one or more protective film layers are attached to the surface of said catalyst-coated membranes in such a way that they overlap with a region of the passive non-coated ionomer area, and with a region of the active area that is coated with a catalyst layer. Furthermore, the present invention discloses a process for manufacture of CCMs and MEAs that contain protective film layers. The materials may be used as components for the manufacture of low temperature fuel cell stacks. | 12-22-2011 |
20120012457 | MEMBRANE ELETRODE UNIT FOR THE ELECTROLYSIS OF WATER - The invention relates to membrane-electrode assemblies for the electrolysis of water (electrolysis MEAs), which contain an ion-conducting membrane having a front and rear side; a first catalyst layer on the front side; a first gas diffusion layer on the front side; a second catalyst layer on the rear side, and a second gas diffusion layer on the rear side. | 01-19-2012 |
