Abstract
The presented invention relates to a cell assembly (100) for the controlled guiding of reactive fluids, wherein: the cell assembly (100) comprises a membrane (101), which has a first side and a second side opposite from the first side; on each of the first side and the second side, a catalyst layer (103) and a microporous layer (105) are disposed; the microporous layer (105) and/or the catalyst layer (103) of at least one side is profiled in such a way that the surface roughness of the catalyst layer (103) differs from the surface roughness of the microporous layer (105), so that the catalyst layer (103) and the microporous layer (105) fit together in parts.
Claims14
A cell assembly (100) for controlled guidance of reactive fluids,
- wherein the cell assembly (100) comprises a membrane (101) having a first side and a second side opposite the first side,
- wherein on the first side and the second side are disposed respectively:
- a catalyst layer (103),
- a microporous layer (105),
- the microporous layer (105) and/or the catalyst layer (103) of at least one side is profiled in such a way that a surface roughness of the catalyst layer (103) differs from a surface roughness of the microporous layer (105), so that the catalyst layer (103) and the microporous layer (105) fit together in parts.
A manufacturing method (300) for manufacturing a cell assembly (100),
- wherein the manufacturing method (300) comprises:
- disposal (301) of a microporous layer (105) on a catalyst layer (103) of a membrane (101),
- wherein the microporous layer (105) and/or the catalyst layer (103) is or are profiled on at least one side such that a surface roughness of the catalyst layer (103) differs from a surface roughness of the microporous layer (105), so that the catalyst layer (103) and the microporous layer (105) fit together in parts.
