- the ratio of these stretching ratios, the type of pore-forming agent, the blending amount, the molecular weight of the resin constituting the porous substrate, and the like determine the shape of the holes formed in the film.
- a more preferable production method is biaxial stretching. This is because, in the uniaxial stretching method, a defect is likely to occur if a strong force is applied when the substrate is torn or immediately attached to an electrode or incorporated into a fuel cell.
- the porous substrate used in the present invention is preferably a material that does not substantially swell with respect to methanol and water, particularly when dried. It is desirable that there is little or almost no change in area when wet by water.

- the liquid can dissolve the surfactant, and the hydrophobic part in the surfactant is also present on the substrate surface. Since it has a good affinity for the solvent, it is difficult to attach the hydrophobic part to the substrate surface. In addition, even if it adheres to the surface of the substrate, it is thought that it is immediately washed away with a solvent and the amount of adhesion is small and non-uniform as shown in Fig. 5.
- the liquid for dispersing the surfactant is preferably an aqueous liquid, more preferably a mixed liquid containing 50% by mass or more of water.
