SYSTEM FOR PREHEATING A FUEL CELL FOR A FUEL CELL VEHICLE AND A METHOD OF CONTROLLING SAME

Proposed are a system for preheating a fuel cell for a fuel cell vehicle and a method controlling the system. An information collector collects start pattern information regarding a start pattern of a driver including start dates, positions, and times of a fuel cell vehicle when the vehicle is started. A controller classifies a start date in the start pattern information of the driver as a weekday group or a weekend group, classifies a start position in which the start of the vehicle is concentrated as a position group, classifies a start time in which the start of the vehicle is concentrated as a time group, deduces a predicted next start time based on each group when the vehicle is stopped, and controls a temperature increase of a fuel cell based on the predicted next start time when the fuel cell is stopped.
