Portable chemical hydrogen hydride system
First Claim
1. A hydrogen generator comprising a fuel tank, a wicking material in the fuel tank, a fluid in the wicking material, a hydrophilic membrane bounding the wicking material for receiving the fluid from the wicking material by a wicking pressure, a surface proximal to the hydrophilic membrane, a catalyst on the surface, and hydrogen generated by hydrolyzation of the fluid contacting the catalyst due to reduced internal pressure.

Abstract
A hydrogen source system delivers a controlled fuel stream to applications, using wicking to control the contact between a mixture of NaBH4, NaOH and H2O and a hydrolyzing catalyst to create a feedback mechanism to automatically maintain a constant pressure production supply of hydrogen. A small compact device packaged for storage, the system operates in any orientation and is mobile. The system is a small portable packaged hydrogen generator for small fuel cells to power applications that are currently powered by batteries. These packaged devices have higher energy per unit mass, higher energy per unit volume, are more convenient for energy users, environmentally less harmful, and less expensive than conventional power sources.

- 35. A hydrogen generation process comprising providing a fluid and a catalyst in a fuel tank, contacting the fluid and the catalyst, causing dehydrogenation of the fluid on contacting with the catalyst, generating hydrogen, coupling a pressure of the generated hydrogen to a mechanical means, causing bubble formation and capillary wetting for positioning the fluid.
