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.
