Abstract
A method for manufacturing a membrane assembly for a fuel cell, which membrane assembly includes a membrane with a catalyst layer and a frame arranged on the same side of the membrane and a gap between the catalyst layer and the frame. To allow an easy and cost-effective way for manufacturing such a membrane assembly, the manufacturing method may include the following steps:
