A fuel cell is operatively connected to, and powers an electronic device. The fuel cell includes at least one electrode and an electrolyte in electrochemical contact with the electrode(s). A mechanism is provided for delivering fuel to the fuel cell while powering the electronic device.

Method and apparatus for fueling fuel cells

An ink supply station for use with a first ink supply and a second ink supply includes a first module and a second module releasably coupled to the first module. The first module includes a first chassis and a first movable member supported by the chassis, wherein movement of the member causes flow of ink from the first ink supply. The second module includes a second chassis and a second movable member supported by the second chassis. Movement of the second member causes flow of ink from the second ink supply.

Printer ink supply system

A fluid transport conduit for conveying ink-jet ink from a reservoir to a printhead in an ink-jet printer is provided. The fluid transport conduit comprises at least one inner layer, such as high density polyethylene, cyclic olefin copolymer, or polypropylene homopolymer, that is flexible and is a barrier to liquids, and at least one outer layer, such as nylon or polyvinyl alcohol, that is a barrier to air and is softer, or more compliant, than the inner layer, with the inner layer bonded to the outer layer. The two layers are advantageously co-extruded to form the fluid transport conduit.
