Abstract
The present invention provides an idle stop-start control method of a fuel cell hybrid vehicle including a fuel cell as a main power source and a storage means as an auxiliary power source, in which air and hydrogen supply is cut off during low power operation where the efficiency of the fuel cell is low and during regenerative braking such that residual oxygen and hydrogen are consumed to drop the voltage of a fuel cell stack, thus stopping the operation of the fuel cell.
