Metal bipolar plate manufacturing device and method

Abstract

The invention discloses a metal bipolar plate manufacturing device and method. The metal bipolar plate manufacturing device comprises a capacitor bank, a background field coil, an upper forming die, alower forming die, an upper table base, a lower table base, an upper slab, a lower slab and an insulating plate; the upper slab and the lower slab are symmetrically distributed on the two sides of the insulating plate, the upper forming die is distributed above the upper slab, and is used for restraining the forming shape of the upper slab, and the lower forming die is distributed below the lowerslab, and is used for restraining the forming shape of the lower slab; the capacitor bank discharges the upper slab and the lower slab, so that mutually exclusive electromagnetic force is generated between the upper slab and the lower slab, and the upper slab and the lower slab are driven to deform to form a bipolar plate; and the capacitor bank discharges the coil of the background field after charging, so that a background magnetic field for the forming of the upper slab and the lower slab is provided, and after the distance between the upper slab and the lower slab in the forming process is weakened, the background magnetic field provided by the background field coil can still be continuously changed to form the bipolar plate. According to the metal bipolar plate manufacturing device,a bipolar plate forming device is simplified.

Description

technical field [0001] The invention relates to the technical field of metal manufacturing, and more specifically, to a metal bipolar plate manufacturing device and method. Background technique [0002] In recent years, with the depletion of petroleum energy and climate change, fuel cells have aroused great interest due to their advantages of high efficiency, fast start-up, great potential for energy saving, safety and environmental protection, and are considered as an alternative to internal combustion engines in transportation applications. main candidate power supply. The proton exchange membrane fuel cell is mainly composed of three parts: porous gas diffusion electrode, proton exchange membrane and bipolar plate. 80% of the total mass of the entire fuel cell stack and 45% of the total cost have become the main bottleneck restricting the marketization of fuel cells. Therefore, the research and development of bipolar plates play a vital role in the development of proton...

Problems solved by technology

However, since most of the currently used metal bipolar plate materials are stainless steel, in order to overcome its low conductivity electromagnetic forming needs to be driven by a driving piece, and in order to solve the problem that the driving piece cannot be reused, it is necessary to separate the driving piece and the slab pia mater
