1. A hydrogen fueling station comprising:
- an enclosure having an external air inlet and a ventilation air outlet;
a plurality of hydrogen storage tanks located within the enclosure;
process components located within the enclosure and in fluid communication with the tanks, for supplying and dispensing pressurized hydrogen gas to and from the tanks;
an electrical component housing located within the enclosure, and comprising a pressurization air inlet;
a controller housed within the electrical component housing and communicative with the process components, for controlling the supplying and dispensing of hydrogen gas to and from the tanks; and
a ventilation assembly comprising a ventilation air flow path extending from the external air inlet to the ventilation air outlet, the tanks and process components being located within the ventilation air flow path; and
a fan located in the air flow path near the external air inlet and upstream of the tanks and process components, and operable to direct air through the air flow path at a rate that maintains the leaked hydrogen concentration in the air flow path_below a selected threshold, and to direct air through the pressurization air inlet such that an above-ambient air pressure is maintained inside the electrical component housing.

Abstract
A hydrogen fueling station and system for hydrogen fueled vehicles that can transfer any gaseous fuel to any vehicle and can be located in any place where a vehicle can park and where environmental, safety and other regulatory requirements permit gaseous fuel to be transferred. The hydrogen fueling station is vertically elongate and includes an enclosure that has a plurality of housings to house groups of like components. The housings are configured and positively ventilated with external air to prevent the accumulation of leaked hydrogen.
