An electro-galvanic hydrogen generator system that has two or more anode materials; a cathode material; and an electrolyte. The electrolyte comprises a metal hydride, at least one stabilizing agent, and a solvent. Hydrogen gas is generated whenever an anode material and the cathode material are electrically connected, and the different anode materials can be used separately or in combination to control the quantity and rate of hydrogen generation. An insulating shield may be used to catch reaction debris from the anodes. A removable inert layer may cover the electrodes. The use of cell pressure may regulate the rate of hydrogen generation. The hydrogen generator may have a separate catalyst chamber, and the hydrogen generator may also function as a battery.
