INTEGRATED NOISE ATTENUATING VOLUME FOR FUEL CELL SYSTEM

A multi-function fuel delivery system, a method of providing fuel delivery and a noise-attenuating and fuel injector housing device address a root cause of audible noise in a fuel delivery system by placing a sufficiently sized volume directly at the inlet of pulsed-type hydrogen injectors, thereby eliminating pressure pulsation and audible noise created by pressure pulsations. By combining a noise-attenuating function and a fuel supply rail capable of supplying hydrogen to multiple injectors with both performed within a single volume addresses space-related and cost-related challenges as well as other challenges of the fuel delivery system.
