ABSTRACT:
The invention provides a rigid reusable transport and storage vessel for retaining a plurality of anode cassettes of pressed zinc particles saturated with aqueous alkaline solution, and utilizable as an electric fuel in a zinc-air battery, the vessel having a sealably covered aperture and being provided with a hydrogen recombination device, the device being provided with an external surface at least part of which projects into the air surrounding the vessel for venting any hydrogen produced by the anode cassettes into the air surrounding the vessel, and the vessel being internally compartmentalized to contain a plurality of sealable internal compartments for retaining the plurality of anode cassettes, each of the internal compartments being provided with a gas non-return valve venting from the internal compartment to an interior space of the vessel for venting generated hydrogen from the cassettes via the gas non-return valve to the vessel for elimination via the hydrogen recombination device while preventing ingress of air to the internal compartments, whereby hydrogen internally generated and emitted from the vessel is safely combined with the oxygen in the air surrounding the vessel, thus eliminating potentially explosive hydrogen.
