Abstract

The invention discloses a light self-temperature-equalizing bipolar plate based on foam metal and a preparation method thereof. The bipolar plate structure comprises a plate body, a shell and the foammetal, wherein the shell is arranged to be of an outer layer structure of the plate body, the foam metal is arranged to be of an inner layer structure of the plate body, a cavity of the foam metal isfilled with a phase change material, heat generated by an overheating area is stored through the phase change material, the heat transfer process is enhanced through the foam metal, and problems thatthe phase change material is small in heat conductivity coefficient and long in heat charging time are solved. The bipolar plate structure is advantaged in that heat stored in the phase change material can provide heat for the process of battery restart to reduce the corresponding time, the foam metal material is adopted as a raw material for manufacturing the bipolar plate of the fuel cell, moreover, a shell is formed through laser sintering, and manufacturing process difficulty of the bipolar plate is reduced through the laser sintering technology.
