Abstract: A method for determining the flow of an anode gas out of an anode sub-system. The method includes providing pressure measurements at predetermined sample times over a predetermined sample period and using the pressure measurements to calculate a slope of a line defining a change of the pressure from the beginning of the time period to the end of the time period. The slope of the pressure line is then used in a flow equation to determine the amount of gas that flows out of the anode sub-system, which can be through a valve or by system leaks.

Abstract translation: 一种用于确定阳极子系统中的阳极气体的流动的方法。 该方法包括在预定采样周期内以预定采样时间提供压力测量值，并使用压力测量来计算从时间段开始到时间段结束时限定压力变化的线的斜率。 然后在流量方程中使用压力线的斜率来确定从阳极子系统流出的气体量，其可以通过阀门或通过系统泄漏。
