A hydrogen supply system for a fuel cell, which is small and discharges almost no carbon dioxide. The hydrogen supply system includes a fuel chamber for storing isopropyl alcohol (IPA), a dehydrogenation reactor for forming hydrogen gas and acetone gas from IPA, a gas-liquid separator for separating hydrogen gas from acetone liquid, and a recovery chamber for storing the acetone liquid. The separated hydrogen gas is supplied to the fuel cell. |
