A fuel cell is formed by sandwiching a membrane electrode assembly between a first separator and a second separator. An outlet connection channel connecting a fuel gas flow field with a fuel gas discharge passage is provided in the first separator. The outlet connection channel has a plurality of discharge holes extending through the first separator. The discharge holes are arranged in the direction of gravity. The discharge hole at the lowermost position has an opening elongated downward to have an opening area larger than opening areas of the other discharge holes above and adjacent to the discharge hole at the lowermost position.
