Thermal Management System of Fuel cell vehicle stack is important technology for improving stack output efficiency and cold start performance. Rapid coolant heating apparatus is device which raise coolant temperature of FCEV stack to help optimized stack temperature level with high voltage electric heaters. In this study, CFD analysis of internal heat and mass transfer characteristics for rapid heating apparatus is conducted and obtain pre-design factors with temperature profile on electric heater surface and velocity profile of coolant flow. With design change of electric heater location and coolant flow distributer, coolant distribution rate is improved within 1.3% between two outlet ports and 200K temperature down effect on heater surface.
