1. A start control system of a fuel cell, the start control system comprising:
the fuel cell configured to generate power upon receiving air and fuel;
an air supply system configured to supply the air to a cathode of the fuel cell through an air supply line;
a fuel supply system configured to supply the fuel to an anode of the fuel cell through a fuel supply line;
an air controller configured to control the air supply system such that the air flowing into the air supply line bypasses the cathode of the fuel cell when a start ON signal is input; and
a fuel controller configured to supply a new fuel to the fuel supply line when the start ON signal is input and to control the fuel supply system to purge fuel of the fuel supply line in a state where the air of the air supply line bypasses the cathode of the fuel cell.
