  • Publication number: 20230253593
    Abstract: A layered film is prepared by layering a substrate layer, a first layer containing an acid-modified olefin-based resin, a second layer containing a cyclic olefin-based resin, and an ion-exchange resin-containing layer containing an ion-exchange resin in this order. Each of the second layer and the first layer may be a layer formed by coating. The average thickness of the second layer may be 30 ?m or less. A membrane electrode assembly of a solid polymer-type fuel battery may be produced by releasing a layer other than the ion-exchange resin-containing layer from the layered film. The layered film does not contain a component having a large environmental load even when the release layer is formed of the cyclic olefin-based resin, firmly attaches to a substrate, and can be released smoothly from the ion-exchange resin-containing layer serving as a transfer medium.
