摘要： PROBLEM TO BE SOLVED: To reduce a sense of incongruity accompanying vehicle running after securing effectiveness of moisture discharge from a fuel cell.
SOLUTION: The fuel cell mounted vehicle 10 performs moisture discharge for reducing residual amount of water in the cathode after increased supply of air in the air supply system 140 in acceleration status, and stops moisture discharge at a deceleration status (Steps S400-410, Steps S370-390). On top of that, in vehicle acceleration, a threshold for determining appropriateness of discharge of the residual water is made large on the low speed side and made small on the high speed side. Thereby, even in performing moisture discharge under the vehicle acceleration state, the frequency of implementation of increased supply of air for moisture discharge in the low speed side is made less. Furthermore, in vehicle deceleration, the moisture discharge is interrupted and the implementation frequency of supply of air is made less than that in acceleration.

摘要翻译：要解决的问题：在确保来自燃料电池的湿气排放的有效性之后，减少伴随车辆行驶的不协调感。解决方案：燃料电池安装车辆10在加速状态下增加空气供应系统140中的空气供应之后进行湿气排放，以减少阴极中的剩余量，并且以减速状态停止水分排放（步骤S400- 410，步骤S370-390）。此外，在车辆加速中，在低速侧使用于确定残留水的排放适当性的阈值<2>在高速侧变小。因此，即使在车辆加速状态下进行湿气排放，也能够使低速侧的排水用空气供给量增加。此外，在车辆减速时，中断了排气，空气供给的实施频率小于加速时的排气量。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system capable of appropriately correcting map data showing the correlation between AC impedance and water content.
SOLUTION: The fuel cell system is equipped with map data 94 showing the correlation between the AC impedance and the water content of a fuel cell; and a correction part 95 correcting an error of the map data 94 based on the water content calculated by income and expense calculation and actual measurements of AC impedance of the fuel cell. A dead zone region where an AC impedance value does not vary when the water content exceeds a prescribed value is present in the correlation between the AC impedance and the water content. Since a value of the AC impedance becomes almost constant independent of the water content in the dead zone region, the correction part 95 utilizes the dead zone characteristics and can accurately correct the map data even when the estimated accuracy of the water content is low.

摘要翻译：要解决的问题：提供能够适当地校正表示交流阻抗与水分含量之间的相关性的地图数据的燃料电池系统。解决方案：燃料电池系统配备有地图数据94，示出了AC阻抗和燃料电池的含水量之间的相关性; 以及基于由收入和费用计算计算出的含水量和燃料电池的AC阻抗的实际测量来校正地图数据94的误差的校正部分95。当AC阻抗和含水量之间的相关性中存在水含量超过规定值时AC阻抗值不变化的死区区域。由于AC阻抗的值变得几乎恒定，与死区区域中的含水量无关，所以校正部95利用死区特性，即使在估计的含水量的精度低的情况下也能够精确地校正地图数据。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system capable of improving output performance of a fuel cell directly after startup.SOLUTION: When an operation start of a fuel cell system 1 is instructed, a control device 7 accesses a measurement impedance memory 70, and reads out measured impedance stored at a previous system stoppage. Then, the control device 7 compares the read-out measured impedance and reference impedance stored in a reference impedance memory 51. If the measured impedance exceeds the reference impedance, the control device 7 determines that a drying process is already done at the system stoppage, and sets the system Ready On after executing humidification treatment.

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system capable of suitably controlling a moisture volume of the fuel cell by accurately detecting a moisture condition of the fuel cell.
SOLUTION: An FC outlet temperature change velocity detection part 180 detects FC outlet temperature change velocity in a unit time based on FC outlet temperature detected by a temperature sensor. The FC outlet temperature change velocity detection part 180 sends an impedance measuring command to an impedance calculating part 140 if the detected FC outlet temperature change velocity is judged to be under a change velocity standard value stored in a memory 153. The impedance calculating part 140 carries out the second impedance measuring when it receives an impedance measuring command from the FC outlet temperature change velocity detection part 180. With this, by the minimum number of impedance measuring times (for instance, twice), a scavenging control for retaining a moisture volume of a fuel cell 40 at a proper level can be realized.

摘要： PROBLEM TO BE SOLVED: To assure the starting of a fuel cell at a next time even if an abnormality occurs with a bypass function of a humidifier.
SOLUTION: A humidifier 76 is provided with a bypass channel 78, and a bypass opening/closing valve 79 is provided in the bypass channel 78. The air from an air compressor 75 is supplied to a fuel cell 20 by the channel of the bypass channel 78, for scavenging. If, at that time, the detected pressure of a pressure sensor 73 is higher than the reference value and an abnormality is detected in the bypass function of the humidifier 76, a target moisture content of the fuel cell 20 is reduced during normal operation, so that the moisture content at the start of scavenging is reduced by such amount as the target moisture content has been reduced. So, at the next starting time, the fuel cell 20 is surely started with no freezing.
