摘要： A method of shutting down a fuel cell system includes a first step of supplying hydrogen gas and air to a fuel cell stack to thereby cause the fuel cell stack to generate electricity, and a second step of stopping supply of the hydrogen gas, and then supplying air to the fuel cell stack so as to cause the fuel cell stack to generate electricity upon detection of a command to shut down the fuel cell stack. In the second step, when the pressure of the hydrogen gas is lowered to a preset lower-limit value based on an anode pressure, which actually is measured, the fuel cell stack is caused to stop generating electricity.

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。

摘要： A fuel cell system includes a replacing unit for replacing a gas remaining in the anode of the fuel cell with the anode gas supplied anew by the anode gas supply unit when starting up the fuel cell. The amount of the anode gas is set to be lower, if the operation condition determining unit determines that the last operation was performed in a low-temperature and short-time operation mode. The operation condition determining unit sets the amount of the anode gas so that the gas remaining in the anode can be replaced with the anode gas with an entire anode capacity if the anode was been scavenged while no electro-chemical reaction was progressing in the fuel cell. The present invention can set the amount of anode gas appropriately when starting up the fuel cell.

摘要： A scavenging process is performed on the anode side by opening an air supply valve to remove liquid droplets in a fuel gas flow field using the compressed air from an air compressor. During the scavenging process, when a start up signal from an ignition switch is received, the start up of a fuel cell is prohibited until the gas in the fuel gas flow field is replaced completely by air.
