Abstract
Piping interconnecting a fuel cell and a humidifier is laid with a rising gradient from the end on the humidifier side of the piping toward the end on the fuel cell side of the piping. The piping is first bent vertically downward and then vertically upward, and this forms a water containing trap in the piping. Problems caused by freezing of condensed water occurring in the piping can be avoided.
