Abstract: The present disclosure pertains to an unmanned aerial vehicle system. Some exemplary implementations may include: a mounting frame (110) onto which at least a payload (30) is affixed; a plurality of fuel cell stacks (50) operable in a predefined configuration, each of the plurality of stacks (50) being in a separate package; one or more tanks (60) configured to supply hydrogen tot the plurality of stacks; a propulsion system (70, 80) configured to receive an out put power generated from the plurality of stacks (50); and a power controller (40) configured to couple the plurality of stacks in the predefined configuration.

Abstract: The application relates to a fueling station for a fuel generator having a fuel generator reservoir, the fueling station comprising: a station reservoir (11) for storing at least one reactant for fuel generation; a fueling interface (14) configured to engage with the fuel generator reservoir and dispense the at least one reactant to the fuel generator reservoir; and a controller (18) configured to: receive a parameter indicative of an intended use of the fuel generator; and control the fueling interface to dispense the at least one reactant in accordance with the parameter.

Abstract: The disclosure relate to a hydrogen generator comprising a reactant cartridge and a reaction chamber. The reactant cartridge comprises a reactant reservoir comprising a first reactant for generating hydrogen gas; and an engagement mechanism configured to engage with a reaction chamber and enable the first reactant to pass from the reactant reservoir to the reaction chamber when the cartridge is engaged with the reaction chamber. The reaction chamber comprises: a reaction chamber for storing a second reactant; and an engagement mechanism configured to engage with the reactant cartridge and enable the first reactant to pass from the reactant cartridge to the reaction chamber when the cartridge is engaged with the reaction chamber.

Abstract: A fuel cell stack assembly (100) comprising a first encapsulation member (102) comprising a first end plate (106) and two side walls (108) extending transversely from the first end plate (106). The distal portion of each of the side walls (108) comprises a lip (110). The fuel cell stack assembly (100) also comprises a second encapsulation member (104) comprising a second end plate (105) and two rims (118). One or more fuel cells (103) located between the first end plate (106) and second end plate (105). Each of the two lips (110) corresponds with one of the two rims (118) to define a bonding plane that extends away from the one or more fuel cells (103).

Abstract: A fuel cell stack assembly comprising: a first encapsulation member (302) comprising a first end plate and two side walls extending transversely from the first end plate; a second encapsulation member (304) comprising a second end plate; one or more fuel cells (330) located between the first end plate and second end plate; and two locking members (310) that are configured to engage with a respective side wall of the first encapsulation member (302) and the second encapsulation member (304), in order to retain the first end plate and the second end plate in a fixed relative position, wherein the side walls of the first encapsulation member (302) are each configured to: engage with the second encapsulation member (304) in order to provide a compression force to the one or more fuel cells (330), and receive the respective locking member (310) in a direction that is parallel to the plane of the one or more fuel cells (330).

Abstract: A fuel cell stack assembly (200) comprising: a first encapsulation member (202) comprising a first end plate (204) and two side walls (208) extending transversely from the first end plate (204); a second encapsulation member (204) comprising a second end plate (205); and one or more fuel cells located between the first end plate (206) and second end plate (205), wherein the side walls (208) of the first encapsulation member (202) are, or the second encapsulation member (204) is, deformable in order for the first encapsulation member (202) to engage with the second encapsulation member (204) and retain the first end plate (206) and the second end plate (205) in a fixed relative position.
