| 摘要 |
The invention relates to a process for producing a membrane-electrode assembly comprising an anode catalyst layer (13), a polymer electrolyte membrane (1) and a cathode catalyst layer (14) and to a fuel cell comprising such a membrane-electrode assembly. The process of the invention comprises the steps of applying a first border (17) comprising a UV-curable material to the polymer electrolyte membrane (1), with an inner region (16) of the polymer electrolyte membrane (1) remaining free of the UV-curable material, applying a catalyst layer (2) which covers the inner region (16) of the polymer electrolyte membrane (1) and overlaps the first border (17), applying a second border (18) comprising the UV-curable material to the first border (17), with the second border (18) surrounding the catalyst layer (2), applying a third border (19) comprising the UV-curable material to the second border (18), with the third border (19) overlapping the catalyst layer (2), and irradiating the first, second and third borders (17, 18, 19) with UV radiation.
