摘要： Disclosed is a fuel cell system, which uses a dead end method and discharges impurities accumulated on the anode side while inhibiting the oxidation reaction of carbon.
In the fuel cell system 1, a fuel cell 2 operates while a passage 8 for a fuel off gas is closed. Impurities accumulated in the passage 8 are discharged when a purge valve 9 opens. When a cell voltage measured by voltage measurement means 11 is not lower than a predetermined value, the present invention activates purge limitation means 13 to avoid a purge. When a cathode potential at which carbon oxidation occurs is X and the maximum anode potential is Y, the predetermined value is equal to X - Y.摘要翻译： 本发明公开了一种燃料电池系统，其使用死端方法并且在积极抑制碳的氧化反应的同时排出积聚在阳极侧的杂质。 在燃料电池系统1中，燃料电池2在用于燃料废气的通道8被关闭的同时运行。 当放气阀9打开时，积聚在通道8中的杂质被排出。 当由电压测量装置11测量的电池电压不低于预定值时，本发明激活清除限制装置13以避免清除。 当发生碳氧化的阴极电位是X并且最大阳极电位是Y时，预定值等于X-Y。
