A fuel cell system arranged to supply electric power to an actuator via an electric power circuit includes an anode and a cathode. A hydrogen delivery system is arranged to supply pressurized hydrogen to the anode, and has a jet pump including an injector nozzle and an ejector. The jet pump channels pressurized hydrogen from a hydrogen tank to the fuel cell. The ejector includes a venturi tube, a mixing chamber, and a secondary flow element, wherein the secondary flow element includes a first duct and a bypass duct. The venturi tube has a first fluidic inlet that is proximal to the injector nozzle, and a second fluidic inlet that is downstream from the injector nozzle of the venturi tube. The first duct is fluidly coupled to the first fluidic inlet, and the bypass duct is fluidly coupled to the second fluidic inlet of the venturi tube.

Fuel cell system and fuel delivery system therefor

Heatsinks and methods are provided for dissipating thermal energy from a substrate in thermal contact therewith. The heatsinks include a plurality of sequentially coupled links. Each of the links includes a hub portion elongated along a central longitudinal axis thereof, a male connector on a first side of the hub portion and elongated along the central longitudinal axis, a female connector on a second side of the hub portion and elongated along the central longitudinal axis, wherein the female connector of each of the links is configured to couple with the male connector of an adjacent one of the links, a planar contact portion on a third side of the hub portion configured to receive thermal energy via conduction from the substrate, and a fin extending from a fourth side of the hub portion configured to dissipate the thermal energy to a surrounding environment via convection.
