<p>An article comprises a containment means supporting pressurized gas-filled microbubbles, the gas being controllably releasable on demand by fracturing the microbubbles. The article of the invention is useful as a fuel or oxidant storage and delivery system to supply electrochemical power devices, such as fuel cells and chemical batteries, particularly those used in portable power applications. Specific applications include a fuel source for a hydrogen/air fuel cell replacement of rechargeable batteries used in portable computers, camcorders and the like, or for powering remote sensing devices.</p> |
