||PCT/EP2014/070190||FRESENIUS MEDICAL CARE DEUTSCHLAND GMBH||HEIDE, Alexander|
The invention relates to a fuel cell
and to a method for producing a fuel cell
from a hollow-fiber membrane module. The fuel cell
according to the invention has a housing (1), in which a bundle (2) of hollow-fiber membranes (3) is arranged. The volume enclosed by the housing (1) is sub-divided into an inlet chamber (7), an intermediate chamber (6), and an outlet chamber (8) by a partition wall (4) tightly surrounding an end-side section (2A) of the bundle (2) of hollow-fiber membranes (3), and by a partition wall (5) tightly surrounding the other end-side section (2B) of the bundle (2) of hollow-fiber membranes (3). The inlet chamber (7) is in fluid connection with the one open ends (3A) of the hollow-fiber membranes (3), whereas the outlet chamber (8) is in fluid connection with the other open ends (3B) of the hollow-fiber membranes (3). The fuel cell
according to the invention is characterized by a simplified electrical connection of all electrically conductive layers (14, 16) forming the anode and the cathode. Thus, the fuel cell
can be produced in high quantities in a cost-effective manner. The connection of the conductive layers (14, 16) forming the anode and cathode to the inner and outer side of the hollow fiber membranes (3) is done by means of a coating (14, 16) of the wall of the housing (1), that is, the two partition walls (4, 5), which define the inlet and outlet chamber (7, 8) and the intermediate chamber (6), with an electrically conductive material.
