    • A coolant reservoir and associated multi-functional unit for a thermal sub-system of a fuel cell system. The coolant reservoir includes a flame arrester positioned in a gas region of the reservoir. The multi-functional unit includes a first pressure relief valve that automatically opens if the pressure within the gas region goes above a first predetermined pressure. The multi-functional unit may also include a second pressure release valve that quickly releases pressure in the coolant reservoir if the pressure within the gas region goes above a second higher predetermined pressure. The multi-functional unit also includes an air-line and a check valve for allowing ambient air to enter the gas region if the pressure within the gas region falls below ambient pressure. The multi-functional unit also includes a cooling fluid fill line having plumbing that causes the coolant reservoir to vent prior to a cooling fluid cap being removed.
    • 一种用于燃料电池系统的热子系统的冷却剂储存器和相关联的多功能单元。 冷却剂储存器包括定位在储存器的气体区域中的阻火器。 多功能单元包括第一压力释放阀,其在气体区域内的压力超过第一预定压力时自动打开。 多功能单元还可以包括第二压力释放阀,其在气体区域内的压力超过第二较高预定压力时快速释放冷却剂储存器中的压力。 多功能单元还包括空气管线和止回阀,用于在气体区域内的压力低于环境压力时允许环境空气进入气体区域。 多功能单元还包括具有管道的冷却流体填充管线,其在冷却流体盖被移除之前使冷却剂储存器排出。
