    摘要: A fuel cell system (100) includes a fuel cell stack (4), a cooling water path (40), a cooling water tank (30), a cooling water pump (10), an oxidant gas supply unit (15), an oxidant gas supply path (11), an oxidant gas humidification path (12), an oxidant gas discharge path (13), and an off-gas path (14). The fuel cell system (100) is configured to control the temperature of a remaining oxidant gas to prevent a cathode (4b) from being filled with cooling water (30r) during the stop of power generation of the fuel cell stack (4) although the inlet of the oxidant gas humidification path (12) is completely submerged in water.

    摘要: Provided is a fuel cell system including a fuel cell module including a first fuel cell and a second fuel cell, and an oxidant gas temperature adjustment device for adjusting a temperature of an oxidant gas supplied to the fuel cell module, the first fuel cell being at least configured to reform a fuel gas, wherein the fuel cell system includes a temperature control means for setting a target temperature of the oxidant gas supplied to the fuel cell module such that a temperature of the first fuel cell and a temperature of the second fuel cell do not exceed a prescribed upper-limit temperature and controlling the oxidant gas temperature adjustment device based on the target temperature, and the temperature control means calculates the target temperature T as T=Tmax-ΔT1-ΔT2 (ΔT1>0), T=Tmax-ΔT2 (ΔT1≤0), or T=Tmax (ΔT2
