Hydrogen gas generating system and method with buffer tank

A hydrogen generating system, comprising:

• a control unit;
• a liquid storage having an intake port for receiving liquid reactant from an external source, an exhaust port for expelling liquid reactant from said liquid storage;
• a liquid heating unit having an exhaust port, an intake port for receiving liquid reactant from said liquid storage, heating elements controllable by said control unit, said liquid heating unit adapted to heat an amount of liquid reactant such that a portion of said liquid reactant enters a gaseous phase;
• a reaction chamber having an intake port in fluid communication with said liquid heating unit exhaust port via a control valve, said control valve controlled by said control unit, said reaction chamber containing a solid reactant and adapted to receive an amount of heated reactant from the said liquid heating unit, which said heated reactant is dispersed through said solid reactant thereby producing at least a product gas, said product gas being at least a mixture of said heated reactant and hydrogen gas, and said product gas expelled from the reaction chamber via a gas outlet;
• a heat transfer means adapted to transfer heat from said reaction chamber to said liquid heating unit;
• and
• a condensation unit having an intake port for receiving said product gas from said reaction chamber, an exhaust port for channeling primarily hydrogen gas out of said condensation unit, said condensation unit adapted to substantially condense said heated reactant
• wherein the system further comprises a buffer tank located downstream of said condensation unit, said buffer tank adapted to receive and store an amount of hydrogen gas, said buffer tank provided with a pressure sensing means and wherein a pressure of said buffer tank is used to ascertain a start and stop of hydrogen gas generation in the said hydrogen generation system.
