Abstract: The present invention relates to a membrane electrode assembly wherein each gas diffusion substrate comprises a porous electrically conductive gasket member is located on the first and second planar faces of a peripheral portion of the sheet material. The electrocatalyst layers are not present adjacent to the gasket members and the edge of the membrane is sandwiched between the gasket members. The invention further relates to integrated cell assemblies and fuel cell stacks comprising membrane electrode assemblies according to the invention.

Abstract: A temporary protective seat cover (10) having a tab (22) attached by means of a pressure sensitive adhesive (24). The seat cover is manufactured from a continuous strip of tubular blow molded plastic, cut and sealed to create upper (b 18) and lower (20) pockets for enclosing a seat back (14) and bottom (16) respectively. The closure tab (22) is a flap cut from the seat cover (10) and has the adhesive strip (24) applied to it. During installation, the closure tab (22) is pulled around the lower portion of the seat back (14) and bonded to the rear portion of the seat cover (10) covering the seat back. This pulls the seat cover (10) taut over the seat bottom (16) in the area of the base of the seat back to prevent slippage and tearing during use.
