Abstract: There are provided a mold release film having excellent handleability and mold releasability even when used in a high-temperature environment, a laminate thereof, and an application thereof. A mold release film is prepared to include at least a substrate layer and a mold release layer directly or indirectly layered on at least one surface of the substrate layer. The mold release layer contains a polypropylene-based resin. The mold release film may have a thermal shrinkage rate of approximately 4.0% or less when subjected to a heating treatment under conditions of 160°C and 15 minutes. Further, a mold release film may be prepared to include at least a mold release layer containing a polypropylene-based resin. The mold release film has a thermal shrinkage rate of 4.0% or less when subjected to a heating treatment under conditions of 160°C and 15 minutes.

Abstract: A membrane electrode assembly includes: a polymer electrolyte membrane; a pair of electrode catalyst layers disposed with the polymer electrolyte membrane therebetween while being in contact with a surface of the polymer electrolyte membrane; and a gas diffusion layer laminated on each of the pair of electrode catalyst layers. The gas diffusion layer includes a microporous layer in contact with the electrode catalyst layer and a diffusion substrate layer made of a fiber substrate. An average fiber diameter of a fiber material contained in the diffusion substrate layer is 10 times or more and 150 times of less of an average fiber diameter of the fibrous substance contained in the electrode catalyst layer.
