The present disclosure provides cell voltage control through oxygen shortage of a fuel cell system. Systems and methods for managing the voltage of a fuel cell during no-load or low-load events are disclosed. The system may employ one or more valves, such as an inlet valve and an outlet valve, to meter fuel (e.g., hydrogen) and/or oxidant (e.g., oxygen) provided to the fuel cell. The voltage or voltage rise may be limited by scarcity of the fuel cell, e.g., oxygen. A controller may be employed to control one or more valves during an idle or low load event, such as start, idle, or stop.
本公开提供了“通过燃料电池系统的氧气匮乏进行电池电压控制”。公开了在空载或低载荷事件期间管理燃料电池的电压的系统和方法。系统可采用一个或多个阀诸如入口阀和出口阀来计量提供给燃料电池的燃料(例如,氢气)和/或氧化剂(例如,氧气)。可通过使燃料电池匮乏例如氧气来限制电压或电压上升。可采用控制器来在空载或低载荷事件诸如起动、怠速或停止期间控制一个或多个阀。
