Abstract
A hydrogen generator employs substantially adiabatic hydrolysis and thermal decomposition of chemical hydrides to provide a controllable generation of hydrogen from a small, lightweight container. The hydrogen generator includes a thermally isolated container for containing a chemical hydride, a preheater to heat the chemical hydride to a predetermined temperature before the chemical hydride is hydrolyzed, a water supply controlled to maintain substantially adiabatic and controlled generation of hydrogen from said chemical hydride, and a buffer to supply an initial flow of hydrogen during generator start-up, absorb excess hydrogen during generator shut-down, and to smooth the hydrogen flow due to changing loads.
