Abstract
This fuel cell stack includes: a coolant-supplying penetration hole and a coolant-discharging penetration hole each communicating with a coolant passage and each penetrates unit fuel cells in a stacking direction. A coolant-supplying penetration hole and a coolant-discharging penetration hole are arranged in a horizontal direction opposing with each other so as to sandwich a power generating region. The fuel cell stack further includes: an air draining penetration hole communicating with the coolant passage and arranged such that at least one part thereof is located at a higher position than an uppermost position of the coolant passage, and penetrates the unit fuel cells in the stacking direction; and a coolant draining penetration hole communicating with the coolant passage and arranged such that at least one part thereof is located at a lower position than a lowermost position of the coolant passage, and penetrates the unit fuel cells in the stacking direction.
