Abstract

The invention discloses a light-weight heat storage bipolar plate and a working method thereof. The light heat-storage bipolar plate includes a cathode plate and an anode plate, and adopts a design in which the flow direction of the cooling liquid is perpendicular to the flow direction of the fuel, which accelerates heat dissipation. The whole field average process overcomes the local overheating problem of the bipolar plate; the invention uses the foam metal material to fill the phase change material to make a bipolar plate with heat storage and light weight characteristics, and at the same time solves the single The problem of slow heat absorption and poor heat absorption effect set by the phase change material accelerates the process of heat being absorbed by the phase change material; the invention can effectively improve the energy utilization efficiency of the reactants, not only output electric energy outward, but also store it through the phase change material The waste heat is used as the thermal insulation heat source during the stack standby process, which not only saves energy, but also improves the quick response characteristics of the stack restart.

Description

technical field [0001] The invention relates to the field of electrochemical reaction devices, in particular to a heat storage lightweight bipolar plate and a working method thereof. Background technique [0002] Due to the characteristics of high emission, high pollution, and low thermal efficiency in the way of utilization of traditional fossil energy, it does not have an advantage in the clean and efficient utilization of energy. New energy and new energy utilization methods have been widely studied at home and abroad, among which electrochemical reaction devices have been paid attention to because of their direct conversion of chemical energy and electrical energy. The electrochemical reaction device includes an electrochemical power generation device represented by a fuel cell and an electrochemical energy storage device represented by a liquid flow battery. Fuel cell is an efficient, clean and pollution-free electrochemical reactor that directly converts chemical ener...
