Problems solved by technology

Therefore, limited by the characteristics of the material, the production of bipolar plates is currently done by manual operation, and it is impossible to realize the automation or semi-automation of the production process.
Due to the use of manual operation, large-scale production cannot be realized, the efficiency is low, and the labor intensity is high, which greatly increases the labor cost in the manufacturing process; and the entire process requires high operating skills of the operators. Consistency cannot be effectively guaranteed

Description

technical field [0001] The invention belongs to the technical field of fuel cells, in particular to a fuel cell flexible graphite bipolar plate mass production system and a production method thereof. Background technique [0002] Hydrogen fuel cell is a kind of proton exchange membrane fuel cell, which is equivalent to the "reverse" device of water electrolysis in principle. Its single cell is composed of bipolar plates and membrane electrodes. The voltage of a single battery is generally 0.3-1.0V, which is very low, so in practical applications, tens or hundreds of single batteries are used in series. Among them, the role of the bipolar plate mainly includes: providing the current path between adjacent single cells, the distribution channel of the reaction gas, the cooling channel, separating the fuel, coolant (water) and oxidant supplied to the single cell, and separating the adjacent cells. Fuel gas and oxidizing gas provide the mechanical strength necessary for the sta...
