Abstract

The invention provides an edge flanging structure for a metal bipolar plate of a fuel cell. The structure comprises a cathode plate, an anode plate, a supporting area (1) and a sealing area (2), the cathode plate lower section (6) is tightly connected with the anode plate lower section (3); the sealing area (2) wraps the cathode plate lower section (6) and the anode plate lower section (3); the anode plate middle section (4) and the cathode plate middle section (7) wrap the supporting area (1), the anode plate upper section (3) and the cathode plate upper section (8) are perpendicular to the supporting area (1), and one end of the anode plate upper section (5) is bent outwards in the direction perpendicular to the anode plate upper section (5) and extends to form an anode plate bent part (51). One end of the cathode plate upper section (8) is bent outwards in the direction perpendicular to the cathode plate upper section (8) and extends to form a cathode plate bent part (81). The invention has the beneficial effects of high reliability and high insulation effect.

Description

technical field [0001] The invention relates to a fuel cell, in particular to an edge flanging structure for a fuel cell metal bipolar plate. Background technique [0002] A fuel cell is a clean energy power generation device that converts chemical energy directly into electrical energy. Because it is an electrochemical reaction, there is no combustion and heat release, and it is not limited by the "Carnot cycle", the energy conversion efficiency is higher than that of ordinary heat engines. It has the advantages of high energy conversion efficiency, simple structure, low emission, low noise, high reliability, etc. It is often used in the power system of vehicles, ships, aerospace and other vehicles, and can also be used as a mobile or fixed power station to generate electricity, etc. The field has a very broad market prospect. [0003] For a traditional bipolar plate fuel cell, its edge structure is simply perpendicular to the support structure, and its external positionin...
