A fuel cell system having a fuel cell stack in a housing includes a compressor providing compressed ambient air to the fuel cell stack and a ventilation system connected to a suction side of the compressor to provide ventilation to the housing and cool an associated voltage monitoring unit, which may be located inside or upstream of the housing. The ventilation system may control the valve to supply air from the compressor outlet to the housing to heat the housing and the stack when either or both of the housing and the stack have a temperature below an associated threshold. The ventilation system may include a second valve to control exhaust gas from the housing based on a temperature of the housing or stack. The stack exhaust may drive a turbine connected to the compressor. The heat exchanger may be positioned to cool compressed air from the compressor prior to the compressed air from the compressor flowing into the stack. 一种具有在壳体中的燃料电池堆的燃料电池系统，包括向燃料电池堆提供压缩环境空气的压缩机以及连接到压缩机的吸入侧以为壳体提供通风并且冷却相关电压监测单元的通风系统，电压监测单
