LAMINATE, MANUFACTURING METHOD THEREOF, AND MANUFACTURING METHOD OF MEMBRANE-ELECTRODE ASSEMBLY OF FUEL BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a laminate which has an ion exchange layer uniform in thickness and formed on a surface of a release layer by coating, and which is superior in heat resistance, and excellent in peelability between the ion exchange layer and the release layer even at a high temperature.SOLUTION: A laminate comprises: a release layer including a polysulfone-based resin; and an ion exchange layer including an ion exchange resin and laminated on at least one surface of the release layer. The polysulfone-based resin may be a polyether sulfone resin. The polysulfone-based resin may have a reduced viscosity of 0.5 or less in a dimethyl formamide solution the concentration of which is 1 g/100 ml at 25°C. The polysulfone-based resin may have a glass transition temperature of 200°C or higher. The ion exchange resin may be a fluorine resin having a sulfonic group in a side chain. The ion exchange layer may consist of an electrolyte film and/or an electrode film.SELECTED DRAWING: None
