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.

Description

technical field [0001] The invention relates to the field of electrochemical reaction devices, in particular to a lightweight self-uniform temperature bipolar plate based on foam metal and a preparation method thereof. Background technique [0002] Energy shortage and environmental protection are two important issues restricting the development of contemporary industrial society. The development and utilization of new energy and its technologies is a major issue in promoting industrial transformation and upgrading, and environmental protection is reflected in the clean utilization of energy in energy utilization. The electrochemical reaction device provides a new way to solve the problem of clean energy utilization. Electrochemical reaction devices include energy supply devices represented by fuel cells and energy storage devices represented by flow batteries. A fuel cell is a device that directly converts the chemical energy of fuel into electrical energy, and is not limi...
