Fuel cell system

The invention provides a fuel cell system. The fuel cell system comprises a circulating system of fuel gas, and the circulating system comprises a linear solenoid valve and an injector which are arranged in parallel. The injector is configured to supply the fuel gas in a lower flow range of required flow ranges of the fuel gas, and the linear solenoid valve is configured to supply the fuel gas in a higher flow range of the required flow ranges. The injector is configured to adjust a supply flow rate of the fuel gas when the required flow rate is in a flow rate region of a flow rate less than a first threshold value, the first threshold value being a flow rate that can be supplied by the injector, and the linear solenoid valve is used for adjusting the supply flow when the required flow is in a flow area equal to or higher than the flow of the first threshold value. 本公开提供一种燃料电池系统。所述燃料电池系统包括燃料气体的循环系统，所述循环系统包括平行布置的线性电磁阀和喷射器。所述喷射器配置为在所述燃料气体的要求流量范围中的较低流量范围中供应所述燃料气体，并且所述线性电磁阀配置为在所述要求流量范围中的较高流量范围中供应所述燃料气体。所述喷射器用于当所述
