Abstract

The invention provides a heat radiation bipolar plate for a fuel battery and belongs to the field of heat control. The heat radiation bipolar plate comprises an oxygen plate and a hydrogen plate, wherein the oxygen plate and the hydrogen plate are buckled to form a hollow structure and are used for storing phase change mediums and radiating heat through phase changes; both the oxygen plate and thehydrogen plate comprise working parts and cooling parts; oxygen distribution runners are arranged on outer surfaces of the working parts of the oxygen plates; hydrogen distribution runners are arranged on outer surfaces of the working parts of the hydrogen plates; insulating coatings are arranged on outer surfaces of the cooling parts and are used for radiating heat outside; phase change medium runners are arranged in the hollow structure. Due to self-circulation cooling of a phase-change medium, the problems that the structure is complex, poor in reliability, and the like because of circulation water cooling, are avoided, and the system reliability is improved.

Description

technical field [0001] The invention belongs to the field of thermal control, and its specific application relates to a heat dissipation bipolar plate for a fuel cell. Background technique [0002] The bipolar plate is an important part of the fuel cell stack. Its main function is to provide gas distribution channels for fuel and oxidant, to isolate oxidant and fuel, and to transfer heat during the electrochemical reaction. The conventional bipolar plate usually includes oxygen plate, hydrogen plate and cooling water heat dissipation system, the outer surface of the oxygen plate is provided with oxygen distribution channels, the outer surface of the hydrogen plate is provided with hydrogen distribution channels, and the cooling water heat dissipation system includes The cooling water channel between the plate and the hydrogen plate, the heat is taken away through the cooling water circulation. [0003] The cooling water heat dissipation system also needs to be equipped with...
