Abstract
The invention relates to a fuel cell stack composed of at least one fuel cell (1) and at least two separator structures (2, 2′). Said separator structures (2, 2′) are open on at least one side towards the exterior in order to allow passive exchange of air. Also, said separator structures comprise a channel system (53, 53′) for guiding fuel. The fuel cell can be embodied as a bi-fuel cell (1) composed of two electric cells. The anodes or cathodes of the two electric cells are arranged opposite each other.
