摘要

The chamber has a fuel gas reserve i.e. hydrogen reserve, including a storage container that stores gaseous hydrogen at pressure ranging from 150 to 850 bar. A rectangular upper wall has an explosion vent that evacuates a portion of fuel gas in case of leakage of the reserve, and limits overpressure within the chamber in case of ignition of fuel gas. The vent has circular openings arranged in an adjacent manner, where surface area of each opening ranges from 0.01 to 0.012 square meter. A fluid cell is provided in fluid communication with the hydrogen reserve.
