  "textContent": "The present invention provides: a laminate for a gasket of a fuel cell, the laminate including a heat seal layer, having excellent moisture and heat resistance, and being suitable for a gasket of a fuel cell; a gasket; a membrane electrode junction including the gasket; and a fuel cell. A laminate includes a base material and a heat seal layer arranged on the base material. The heat seal layer is a reaction product of a heat sealant containing an amorphous polyester polyol (A), an epoxy resin (B), and an isocyanate compound (C). The amorphous polyester polyol (A) is a reaction product of a polyvalent carboxylic acid and a polyhydric alcohol. An amount of aromatic polyvalent carboxylic acid in the polyvalent carboxylic acid is 95% by mass or more. A glass transition temperature of the amorphous polyester polyol (A) is −20° C. or more and 40° C. or less.",
