The invention relates to a heat management method for a proton exchange membrane fuel cell based on array heat pipe phase change heat transfer. The heat management method for the proton exchange membrane fuel cell is characterized by comprising the following step of tightly inlaying array micro-channel heat pipes, which are connected in parallel, onto a fuel cell plate, wherein the pipe diameter of each heat pipe is 0.3cm-0.5cm. The proton exchange membrane fuel cell heat management method provided by the invention has the advantages that the fire-new heat pipe manner is adopted to carry out heat management, a cell is internally radiated through the heat pipes, and the problems that the local overheating is processed and the like are solved; the total temperature drop of the heat pipes is the sum of temperature drop of all parts of a steam flowing channel, an evaporation section and a condensation section, the volume of a wick of each heat pipe is very small, the temperature drop of vapor stream is not large, and the thermodynamic property is good.
