Abstract
A fuel cell and a method for manufacturing a fuel cell from a hollow fiber membrane module. The fuel cell has a housing in which a bundle of hollow fiber membranes is arranged. The volume enclosed by the housing is subdivided into an inlet space, an intermediate space and an outlet space by a partition wall which tightly encloses one end-face portion of the bundle of hollow fiber membranes and a partition wall which tightly encloses the other end-face portion of the bundle of hollow fiber membranes. The inlet space is in a fluid connection with one open end of the hollow fiber membranes, while the outlet space is in a fluid connection with the other open end of the hollow fiber membranes. The fuel cell is distinguished by a simplified electrical connection of all of the electrical layers forming the anode and cathode. As a result, the fuel cell can be produced cost-effectively in large numbers. The conductive layers, forming the anode and cathode, on the inner and outer faces of the hollow fiber membranes are connected by coating the wall of the housing or the two partition walls, which delimit the inlet space and outlet space as well as the intermediate space, with an electrically…
