1. A hydrogen fuel gas generator, comprising:
- a first ampoule having a first reactant stored therein and having a first permeable membrane for passing a vapor from the first reactant out through the first membrane;
a second ampoule having a second reactant therein and having a second permeable membrane for passing vapor from the first ampoule through the second permeable membrane into the second reactant, and for passing hydrogen outward through the second permeable membrane into a container; and
a hydrogen outlet port in the container and a hydrogen conduit connected to the outlet for delivering the hydrogen to a hydrogen consuming device.

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.
