NOVELTY - The heat transfer duct (21) of thermal module (20) is connected between output and input ends (12,13) of water channel of fuel cell module (10). The heat transfer duct (32) of heat recycle module (30) is connected between output and input ends (311a,311b) of chamber (311) of insulation device (31). Starting signal of cell module is detected, and thermal/heat recycle modules are started by control module (40). The heat exchange process is performed between waters in heat transfer ducts so that substance is not transferred between water in cell module and water in device.    USE - System for recycling thermal energy generated from fuel cell module.    ADVANTAGE - The thermal energy generated from fuel cell module can be recycled effectively while optimizing the heat dissipation efficiency, monitoring the environmental temperatures and ensuring heat transfer efficiency. The fuel cell module is allowed to perform electric-chemical reaction under the most suitable temperature so as to achieve the optimal electric energy conversion efficiency. The thermal energy generated from fuel cell module can be effectively applied to heater. The thermal energy can be used effectively without causing pollution to the environment. The damage of heat recycle module can be prevented.    DETAILED DESCRIPTION - The thermal reflux duct (22) is routed from one of three-way valve (213) to heat transfer duct between cooling motor (211) and output end of channel. The heat storage reflux duct (33) is routed from one of other valve (323) to heat transfer duct between heat transfer apparatus (215) and input end of chamber.
