Abstract

The invention discloses an industrial batch production system and method of a metal bipolar plate for a fuel cell, and belongs to the technical field of the fuel cell. The production system is composed of four subsystems in cooperative connection in order: a metal anode-cathode single-pole plate forming system, a bipolar plate processing system, a film-coating system, and a leakage detection system. The industrial batch production system and method of the metal bipolar plate for the fuel cell realizes the industrial batch production and detection of the metal bipolar plate for the fuel cell, thereby accomplishing the conversion of the metal bipolar plate to the industrial production from a laboratory, the consistency of the product quality is achieved through the industrial batch production and the system control on the production process, the production efficiency is improved, the labor intensity is reduced, the manufacturing cost is reduced, and the commercialization and the scale manufacturing of the bipolar plate are realized.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, in particular to an industrial mass production system and method for metal bipolar plates used in fuel cells. Background technique [0002] The proton exchange membrane fuel cell is an electrochemical energy conversion device that can directly convert the chemical energy in hydrogen fuel into electrical energy, and the only product is water. It has the advantages of high efficiency, environmental protection, high power density, and rapid response, and is recognized as an ideal Vehicle power source. [0003] The structure of the fuel cell is simple, and the core components are bipolar plates and membrane electrodes. Bipolar plates are mainly divided into two types according to the material system, namely metal bipolar plates and graphite bipolar plates. At present, graphite plates are the main fuel cell stacks for vehicles in the Chinese market. This type of bipolar plate has high dimensional...
