摘要： A fuel-cell system is provided, which includes a fuel cell, a reactive-gas supply unit and a control unit. The reactive-gas supply unit supplies the reactive gases to the fuel cell. The control unit includes an average stoichiometric flow-ratio calculation part and a reactive-gas reduction part. The average stoichiometric flow-ratio calculation part calculates an average stoichiometric flow ratio by averaging stoichiometric flow ratios. A stoichiometric flow ratio is a ratio of an amount of the reactive gases supplied to the fuel cell with respect to a required amount of the reactive gases of the fuel cell in accordance with a required amount of power generation. When the average stoichiometric flow ratio is equal to or greater than a first predetermined value, the reactive-gas reduction part reduces the amount of the reactive gases supplied to the fuel cell so as to lower the stoichiometric flow ratio.

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 positioning guide is configured to guide a rotational axis of a photosensitive body when a process cartridge is mounted on a main body, and to determine a position of the rotation axis of the photosensitive body with respect to the main body in a mounting state in which the process cartridge has been mounted on the main body. A photosensitive body drive gear is configured to be capable of rotating in a forward and reverse direction and to transmit a rotational drive force to the photosensitive body in the mounting state. A regulating member is configured to be in a lock state and an unlock state. In the lock state, the regulating member prohibits the rotational axis of the photosensitive body from moving in the mounting/removing direction. The rotational axis of the photosensitive body is released from the regulating member in the unlock state.

摘要： An image forming device includes a casing formed with an opening, a pivot member pivotably disposed in the casing so as to be selectively opened and closed, a cover disposed outward of the pivot member, a lock mechanism that maintains a closed state of the pivot member, and a link mechanism. When a first force is applied on the cover to open the cover beyond a predetermined angle, the link mechanism transmits the first force as a second force to the pivot member. The second force is in an opening direction of the pivot member.
