Abstract
A gas exhaust structure of a fuel-cell-powered vehicle includes a recess formed in a rear bumper with a surrounding wall. An opening of the recess is covered with louvers to allow ventilation, thereby to form a chamber. A discharge end of the discharge pipe is mounted to the chamber. An exhaust gas including hydrogen is guided through the discharge pipe into the chamber and is emitted from the opening to the outside of the vehicle.
