Abstract
A study has been made to clarify the performance of road heating system using waste heat of fuel cell. It is important for fuel cell system to improve the general efficiency, therefore, the study suggests that a road heating system utilizes the exhaust heat from polymer electrolyte fuel cell (PEFC) and develops the novel heat utilization system. In a road heating system, required temperature of hot water is between 10℃ and 30℃; exhaust heat of PEFC can be used as heat source because the exhaust heat temperature is more than 60℃. Experiments on a prototype system were conducted to investigate the system performance. The results show that the total efficiency of proposed road heating system is higher than that of conventional system by 7%; the proposed system is effective in snowy cold region.
