Abstract
A system of two fuel ampoules that can deliver a reactant by diffusion through one of the ampoule walls to the other, such that when said reactant enters the second ampoule, it reacts with another reactant in said second ampoule, making hydrogen gas as a product. Both ampoules are stored in a fuel impermeable container. These ampoules used with small low power fuel cells which need a steady controlled uniform delivery of vaporous fuel such hydrogen and alcohols. This fueling system provides a simple safe fuel interactive system for small hydrogen fuel cells that prevents inadvertent hydrogen production by any single ampoule being exposed to water or typical consumer environments.
