Protonenleitende Polymerelectrolytmembran

摘要

The invention relates to a method for producing a polymer membrane (10) that has a thickness in particular of a few micrometres. Said membrane comprises at least one passage (11), preferably a plurality of passages (11) that are in particular uniformly distributed over the membrane (10). According to the invention, a passage (11) has a diameter of less than 500 nm, in particular less than 50 nm; the passage (11) or passages (11) are produced using a template (1); the template (1) comprises a base part (2) with a planar top surface (3), which is provided with a number of columns (4), said number of columns (4) being greater than or equal to the number of passages (11).
