Abstract: A hydrogen gas storage container has a canister with at least one outlet opening for charging and discharging gas, the canister enclosing a metal hydride capable of absorbing and desorbing hydrogen gas and a gauge for measuring the capacity of hydrogen remaining within the hydride material. To further permit distribution of the hydrogen throughout the hydride material, a porous matrix may be disposed within said metal hydride material for providing efficient distribution of hydrogen gas to said metal hydride material. The fuel gauge may further comprise subassemblies for determining the hydrogen capacity, each of which depends for operation on a different property of the metal hydride material.
