Abstract
A fuel cell stack has a multiplicity of individual cells, which each include an anode flow field, a membrane electrode arrangement, and a cathode flow field. Each flow field has a media inlet and channels for carrying the media. The anode flow fields and/or the cathode flow fields have the media inlet on their upward-facing side when used as intended, and are open on their downward-facing side when used as intended.
Claims14
A fuel cell stack, comprising:
- a multiplicity of stacked individual cells, each comprising an anode flow field, a membrane electrode arrangement, and a cathode flow field,
- wherein each of the anode and cathode flow fields has a media inlet and channels configured to carry media,
- wherein the anode flow fields and the cathode flow fields have the media inlet on an upward-facing side of the flow fields, and
- wherein the anode flow fields and the cathode flow fields are open on a downward-facing side of the flow fields such that open lateral edges of the anode flow fields and the cathode flow fields open into a chamber and such that water can escape directly from the open lateral edges to the chamber without having to flow via a pipe.
