Abstract
A device and a method for controlling start-up of a fuel cell vehicle are provided and include a table in which a time-difference between a hydrogen supply initiating time-point and an air supply initiating time-point is recorded for each cooling water temperature at a fuel cell stack outlet. The air supply initiating time-point is adjusted based on the table during the start-up of the fuel cell vehicle to prevent a cell voltage deviation and a cell reverse voltage of the fuel cell stack. A temperature sensor measures a cooling water temperature of a fuel cell stack and a controller adjusts the air supply initiating time-point based on the cooling water temperature of the fuel cell stack during start-up of a fuel cell vehicle.
