| 摘要 |
The present invention provides a laminate that has excellent hot water resistance in high-temperature, high-humidity service environments, can retain its reinforcing effect for an extended period, and is suitable as a reinforcing member for an electrolyte membrane of a solid polymer fuel cell. Specifically, provided is a laminate comprising: a base material formed from a syndiotactic polystyrene resin composition; and a heat-sealing layer placed on at least one surface thereof, wherein the heat-sealing layer has two different melting points (Tm1, Tm2), with Tm1 being 50-120°C and Tm2 being 125-200°C. |
