HYDROGEN GENERATION SYSTEM, METHOD FOR GENERATING HYDROGEN USING SOLID HYDROGEN FUEL AND METHOD FOR PROVIDING HYDROGEN FOR FUEL CELL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen generating system having a solid hydrogen fuel, a liquid absorbing material and phase-change material.

SOLUTION: When the liquid (usually water, alcohol, or aqueous solution of alcohol, aqueous solution of salt or aqueous solution of acid) in the absorbent material contacts with the solid hydrogen fuel, the solid hydrogen fuel reacts with the liquid to release hydrogen and generate heat. When the generated heat is accumulated, a phase-change material raises a reaction temperature and increases a speed of releasing hydrogen. For stabilizing the reaction temperature, the phase-change material which absorbs and accumulates the reaction temperature is disposed adjacent to the solid hydrogen fuel.
