A hydrogen supply system for a fuel cell (1), which isnsmall and discharges almost no carbon dioxide. The hydrogennsupply system includes a fuel chamber (13, 13a, 13b, 13c, 13d,n13e) for storing isopropyl alcohol (IPA), a dehydrogenationnreactor (24, 54,77, 106, 145, 186) for forming hydrogen gasnand acetone gas from IPA, a gas-liquid separator (20, 27, 32,n33, 34, 88, 90, 91, 101, 110, 120, 140, 146, 147, 152, 153,n155) for separating hydrogen gas from acetone liquid, and anrecovery chamber (14, 14a, 14b, 14c, 14d, 14e) for storing thenacetone liquid. The separated hydrogen gas is supplied to thenfuel cell. |
