摘要： PROBLEM TO BE SOLVED: To effectively restrain performance degradation of a fuel cell, and shorten time needed for operation stoppage of a system. SOLUTION: While oxygen remaining at a cathode 1b side is fully consumed by current extraction from a fuel cell stack 1 by a current extraction part 31, an air system inlet valve 23 and an air system outlet valve 24 are closed to restrain ingress of outer air into a regulated zone. Here, closing of the air system inlet valve 23 and the air system outlet valve 24 is to be carried out after an anode pressure is boosted above atmospheric pressure and higher than a cathode pressure. With this, oxygen consumption speed at a cathode 1b side can be heightened without adversely affecting an electrolyte film of the fuel cell stack 1, so that time needed for stoppage of the system can be shortened.

摘要翻译：要解决的问题：有效地抑制燃料电池的性能下降，并缩短系统的操作停止所需的时间。解决方案：当通过电流提取部分31从燃料电池堆1的电流抽出完全消耗在阴极1b侧剩余的氧气时，空气系统入口阀23和空气系统出口阀24关闭以抑制入口的外部空气进入调节区。这里，空气系统入口阀23和空气系统出口阀24的关闭将在阳极压力升高到高于大气压并高于阴极压力的情况下进行。由此，可以提高阴极1b侧的氧消耗速度，而不会对燃料电池堆1的电解质膜产生不利影响，从而可以缩短系统停止所需的时间。版权所有（C）2009，JPO＆INPIT
