  • Patent number: 11563226
    Abstract: A membrane-electrode assembly including a polymer electrolyte membrane, and electrocatalyst layers disposed on both surfaces of the polymer electrolyte membrane, with a total light transmittance measured after delamination of both the electrocatalyst layers by using an adhesive member is 40% or less. The total light transmittance is at an electrocatalyst layer located part, when a total light transmittance at an electrocatalyst layer non-located part is taken to be 100%. The viscous member has an adhesive force of 3 N/10 mm or more when measured by pulling the viscous member adhered to a stainless steel in a 180°angle direction relative to the stainless steel, for delamination from the stainless steel.

  • Patent number: 11516911
    Abstract: A glass circuit board includes, on a glass substrate, a stress relief layer, a seed layer, and an electroplated layer including copper plating. The stress relief layer is an insulator formed by dry coating method and applies a compressive residual stress to the glass substrate at room temperature. The stress relief layer thus reduces cracking, fracturing or warpage of the glass substrate caused by thermal expansion and shrinkage of the copper plating due to heating and cooling of the glass circuit board during manufacturing or thermal cycling, ensuring high connection reliability of the glass circuit board.
