摘要： A first separator of a unit cell and a second separator of another unit cell and are disposed adjacent to each other in a stacked assembly. Crest surfaces of straight sections of first hollow ridges of the first separator are in contact with crest surfaces of second hollow ridges of the second separator, and crest surfaces of bent sections of the first hollow ridges are spaced from crest surfaces of the second hollow ridges. The spaced crest surfaces allow first troughs of the first separator and second troughs of the second separator to communicate with each other, providing communication passages between the first separator and the second separator. Cooling water is passed through the communication passages.

摘要： Upon stop of electric power generation of a fuel cell a hydrogen shutoff valve is closed, and a cathode is purged. At the same time, an air introducing valve and the purge valve are opened. The air taken in by the compressor is introduced into the anode through the air introducing tube to exhaust the hydrogen remaining in the anode to replace the hydrogen with the air. When the replacement of the hydrogen with the air has been finished, the compressor is turned off and the air introducing valve and the purge valve are opened. After that, if a temperature of the fuel cell is determined to be equal to or lower than a threshold “a”, a cathode-prioritized purge and an anode-prioritized purging are performed.
