摘要： A fuel cell system includes a fuel cell, a fuel gas passage, and an oxidant gas passage. The fuel cell includes a solid polymer membrane, a fuel electrode, and an oxidant electrode. A coolant flows into the fuel cell via a coolant passage to adjust a temperature of the fuel cell. An oxidant gas outlet temperature detector is configured to detect an outlet temperature of an oxidant gas discharged from an outlet of the oxidant gas passage. A coolant temperature detector is configured to detect a temperature of the coolant passing through an inlet or an outlet of the coolant passage. A dry-up controller is configured to decide that the solid polymer membrane is in a dry-up state when a temperature difference between the temperature of the coolant and the outlet temperature of the oxidant gas exceeds a first threshold value.

摘要： A fuel cell system calculates amount of fluid discharged from a fuel gas circulation path with water and fuel gas in accordance with an ordinary process map if inside an anode is not scavenged when a fuel cell stops electrochemical reaction; measures amount of water remaining in a fuel gas circulation path in accordance with cumulative electricity output, temperature, or elapsed time after starting the electrochemical reaction if the inside the anode is scavenged previously; and determines whether the inside the fuel gas circulation path is in dry condition or humid condition. The fuel cell system calculates amount of fluid discharged from the fuel gas circulation path with water or the fuel gas in accordance with a map predetermined for the dry condition if the fuel cell system determines that the inside the fuel gas circulation path is in the dry condition. The fuel cell system calculates the amount of the fluid to be discharged with the water or the fuel gas in accordance with the ordinary map if the fuel cell system determines that the inside the fuel gas circulation path is in the humid condition. Accordingly, wasteful discharge of fuel gas can be prevented in a purging operation after starting up the fuel cell system.

摘要翻译： 当燃料电池停止电化学反应时，燃料电池系统根据常规工艺图计算从燃料气体循环路径排出的与燃料气体循环路径排出的流体，如果阳极内部没有被清除; 如果先前清除了阳极内部，则根据累积电力输出，温度或开始电化学反应后的经过时间来测量燃料气体循环路径中剩余的水量; 并判断燃料气体循环路径内是否处于干燥状态或潮湿状态。 如果燃料电池系统确定燃料气体循环路径内部处于干燥状态，则燃料电池系统根据预定的干燥条件的映射来计算从燃料气体循环路径排出的与水或燃料气体的流量的量 。 如果燃料电池系统确定燃料气体循环路径内部处于潮湿状态，则燃料电池系统根据普通地图计算用水或燃料气体排放的流体的量。 因此，在启动燃料电池系统之后的清扫操作中可以防止燃料气体的浪费排放。
