Abstract: An embodiment includes a reworkable fuel cell stack in which a first separator and a second separator forming one fuel cell are bonded to a membrane electrode assembly (MEA) by a hot-melt adhesive, the first separator is bonded to a third separator of another fuel cell by a first UV adhesive film, and the second separator is bonded to a fourth separator of yet another fuel cell by a second UV adhesive film, so that, among a plurality of fuel cells, a specific fuel cell that is defective is easily selectively separated from the fuel cell stack, and is easily replaced with a new or replacement fuel cell.

Abstract: Disclosed is a non-destructive inspection method capable of effectively evaluating adhesion quality of an adhesion portion formed between a cell frame and an EGA without damage to parts or deterioration in durability or adhesiveness of parts. In addition, an EGA-cell frame assembly capable of effectively evaluating adhesion quality of an adhesion portion formed between a cell frame and an EGA by the non-destructive inspection method is provided.

Abstract: Disclosed is a membrane-electrode assembly for fuel cells that can improve durability and prevent reduction in a lifespan thereof. The membrane-electrode assembly for fuel cells includes a pair of electrodes, an electrolyte membrane stacked between the electrodes, the which includes a membrane extension member extending outside the electrodes, a sub-gasket bonded to both surfaces of the membrane extension member, which includes an upper gasket and a lower gasket extending outside the membrane extension member and being bonded to each other, and an opening formed in at least one of the upper gasket and the lower gasket so as to discharge water produced during an electrochemical reaction occurring in the electrodes, which is adjacent to the membrane extension member.

Abstract: A film touch sensor is prepared by performing a process in which a separation layer made of a specific component is formed on a carrier substrate, and an insulation film is formed on a transparent conductive film pattern, which is used as a planarization layer, an adhesive layer or a base layer.

Abstract: Provided herein is a touch sensor including: a substrate having a transmittance of 5% or less at a wavelength of 380 nm; a touch sensor layer configured to be opposite the substrate and having a thickness of 2 ?m to 10 ?m; and an adhesive layer disposed between the substrate and the touch sensor layer, wherein the adhesive layer includes a cured product of an adhesive composition including at least one selected from the group consisting of an initiator and a sensitizer having an absorption wavelength in the range of 380 nm to 450 nm and has an adhesion strength of 5 N/25 trim or more. There is an advantageous effect in that the provided film-type touch sensor represents excellent adhesion and folding characteristics even when the substrate has a relative low transmittance.

Abstract: A film touch sensor includes a base film, an adhesive layer, a separation layer and a conductive pattern layer, which are sequentially laminated. The base film has a retardation value Ro in a plane direction of 0 to 10 nm, and a retardation value Rth in a thickness direction of ?10 to 10 nm. When the film touch sensor is applied to a final product, interference between laminates may be minimized to significantly reduce a change in color sense of an image.
