Apparatus, system, and method for generating hydrogen

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.

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.
