Abstract: PURPOSE: A method for controlling condensed water drain is provided to change water amount and state, thereby solving a flooding phenomenon and dry-out phenomenon. CONSTITUTION: A method for controlling condensed water drain comprises a step of calculating a water balance type residual condensed water amount in an anode condensed water collector; a step of determining a warning level of a condensed water level sensor when the residual condensed water amount is larger than a value multiplied of a condensed water density and the whole volume of a condensed water collector; a step of determining the failure of the condensed water level sensor when (V_cell ΔV_cell_TH), (hydrogen recirculation blower RPM inlet normal pressure map + P_TH), or (the outlet pressure of an anode stack > outlet normal pressure map + P_TH); and a step of controlling a drain valve based on anode water trap estimation. [Reference numerals] (AA) Calculating water balance-based residual condensed water in an anode condensed water collector; (BB) Residual condensed water amount[kg] = Σ_t=0^t=∞ [AWT-(Anode condensed water drain valve On) x (Condensed water discharging amount per second)] x Δt + Residual condensed water initial value; (CC) Condensed water level sensor warning; (DD) Drain valve is possibly excessively closed due to the malfunction of a water level sensor; (EE) Cell voltage reduction, hydrogen re-circulation blower abnormal operation, anode side stack input/output pressure abnormality possibly occur due to the intensification of flooding in a stack; (S102) (Residual condensed water amoun > ρ x V1) and (Retention time > t1) ?; (S104) [(V_cell ΔV-cell_TH) or (Hydrogen-recirculation blower RPM Input normal pressure map + P_TH) or (Anode stack output pressure > Output normal pressure map + P_TH)) and [(Retension time > t2)]?; (S105) Condensed water level sensor fail; (S106) Initiating the control of AWT estimated value-based condensed water drain valve(Initial value close); (S107) (Residual condensed water amount > ρ x V2) and (Retension time > t3) ?; (S108) Condensed drain valve open; (S109) (Residual condensed water amount t4)?; (S110) Condensed drain valve close;

Abstract: PURPOSE: A method for starting a fuel cell vehicle is provided to obtain the driving power of fuel cell accessories by boosting the voltage of a low voltage sub battery and a high voltage sub battery. CONSTITUTION: A high voltage DC-DC converter boosts the voltage of the high voltage sub battery of an auxiliary power(S11). A low voltage DC-DC converter boosts the voltage of the low voltage sub battery of the auxiliary power(S13). The final supply voltage is supplied to a fuel cell BOP(Balance of plant)(S14). An auxiliary part for driving a vehicle is driven with the power from a fuel cell stack(S15). A surplus power is charged in the high voltage sub battery through a high voltage DC-DC converter(S16). The surplus power is charged in the low voltage sub battery through a low voltage DC-DC converter(S17). The surplus power is charged in a super capacitor(S18).
