Apparatus, system, and method for generating hydrogen
First Claim
1. A hydrogen generator, comprising:
- a chemical hydride disposed within a water-selective membrane;
an outlet port connected to the water-selective membrane and configured to allow hydrogen to exit the water-selective membrane; and
wherein the water-selective membrane is configured to selectively diffuse water from a fluid to the chemical hydride.

Abstract
An apparatus, system, and method generate hydrogen through a controlled chemical reaction between water and a chemical hydride. The invention includes a chemical hydride isolated from water by a water-selective membrane. A fluid containing water is brought into contact with the water-selective membrane. The water diffuses through the water-selective membrane and reacts with the chemical hydride. The water diffuses through the membrane at a predetermined rate based on a water concentration gradient across the water-selective membrane. The water-selective membrane is substantially impermeable to elements and molecules other than water. Hydrogen generated within the chemical hydride is collected and used in various applications.

8. A hydrogen generator, comprising:
-
a chemical hydride disposed within a housing;
a check valve connected to the housing and configured to allow hydrogen to exit the housing; and
a water-selective membrane configured to separate a fluid comprising water from the chemical hydride, the water-selective membrane selectively diffusing water from the fluid into the chemical hydride to react with the chemical hydride. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for generating hydrogen through a controlled chemical reaction between water and a chemical hydride, the method comprising:
-
providing a chemical hydride;
isolating the chemical hydride from exposure to water by way of a water-selective membrane having an internal surface and an external surface; and
introducing a fluid comprising water to the external surface of the water-selective membrane such that the water-selective membrane selectively diffuses water in the fluid through the water-selective membrane at a constant rate to chemically react with the chemical hydride. - View Dependent Claims (16, 17, 18, 19, 20)
