Description

Technical field [0001] The present invention relates to the field of fuel cell technology, particularly to a fuel cell bipolar plate of flexible carbon-based industrial production process. Background technique [0002] The fuel cell is an electrochemical power source of many, more specifically, the fuel cell is the energy of a chemical reaction directly into electrical energy in a process module. The fuel cell battery generally has a very different and, in general a battery active material is stored in the battery, so that the storage amount of the active material determines the amount of capacity of the battery, the fuel cell active substance can be an endless stream Input. The fuel cell includes a proton exchange membrane fuel cells, alkaline fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells, solid oxide fuel cells and the like. Which is widely used is the proton exchange membrane fuel cell, hydrogen and oxygen especially in the reaction mass exchange membrane...

Problems solved by technology

Therefore, due to the limitation of material characteristics, the current production of flexible carbon-based bipolar plates is done manually, and the production process cannot be automated or even semi-automated.

Due to the manual operation, the whole process requires high skills of the operators, and it is difficult to effectively guarantee the consistency of product quality. At the same time, due to the inability to realize large-scale production, the efficiency is low, the labor intensity is high, and the loss is high, which greatly increases costs in the manufacturing process
