Abstract
A fuel cell stack includes a plurality of unit cells, bypass resistors, and connective resistors. The unit cells are connected in series and/or in parallel. The connected resistors are disposed between the unit cells connected in series and disconnected by heat due to resistance at a small current value in comparison to an current collector. The bypass resistors are connected in parallel to the unit cells or the unit cells connected in parallel.
