Beschreibung
Zusammenfassung:	A fuel cell stack of the present invention includes intermediate current collectors (52, 53) which are disposed in an intermediate portion between a pair of end portion current collectors (50, 51) and are configured to divide anode gas supply manifolds (192I, 392I) and cathode gas supply manifolds (193I, 393I), two or more sub-stacks (P, Q, R) each configured to include one or more unit cells (110, 210, 310) which are stacked between two collectors which are included in a pair of end portion current collectors (50, 51) and the intermediate current collectors (52, 53), anode gas supply inlets (172I, 272I) which are connected to anode gas supply manifolds (192I, 392I) in one of sub-stacks (P, Q, R), and cathode gas supply inlets (173I, 273I) which are connected to cathode gas supply manifolds (193I, 393I) in one of sub-stacks (P, Q, R).
