Abstract
Abstract An apparatus for heating air wherein the combustion is dispersed in direct proximity to a metal hydride fuel storage means in order that the combustion heat effects the release of hydrogen from the metal hydride. The combustion area contains a catalyst and a semipermeable membrane separates the hydride fuel storage means and the combustion area. The temperature of the metal hydride is raised to effect initial release of hydrogen which passes through the semipermeable membrane, mixes with air and is combusted at the catalyst. The heat of combustion, in direct proximity to the metal hydride, perpetuates the hydrogen release.
