A fuel cell system (1000) provided with: a gas discharge flow path (M2, 252) which extends in the stack direction of a stack body (10) and has one end located within a fuel cell stack (100) and the other end located outside the fuel cell stack; and a water discharge flow path (M3, 254) which penetrates through at least a part of the stack body (10) at a position below the gas discharge flow path (M2, 252). The gas discharge flow path (M2, 252) and the water discharge flow path (M3, 254) are communicate with each other within the fuel cell stack (100) through at least one communication section (Mco). The gas discharge flow path (M2, 254) has, on the downstream side of the communication section (Mco), a narrow flow path (251) having a smaller cross-sectional area than the flow paths therearound. The downstream end section (R1) of the water discharge flow path (M3, 254) is connected to the narrow flow path (251). |
