Abstract

The embodiment of the invention discloses a processing device and a processing method for a metal flow field plate of a proton exchange membrane fuel cell. The processing device comprises a top seat,a mounting seat is fixed below the top seat, a horizontal metal plate slot is formed on one side of the mounting seat, a cavity communicating with the metal plate slot is arranged in the mounting seatabove the metal plate slot, and a fastener is arranged on the bottom surface of the mounting seat. A horizontal support is horizontally arranged below the mounting seat, one side of the horizontal support is fixedly connected with a third slider, a fourth sliding rail arranged in the x-axis direction is arranged on the horizontal support, a fourth slider is slidably mounted on the fourth slide rail, a first liner is arranged on the fourth slider, a pressure sensor is arranged on the first liner, a second liner is arranged on the pressure sensor, a displacement sensor is arranged on the secondliner, a third liner is arranged on the displacement sensor, and a microforming die is arranged on the third liner. Using the processing device of the metal flow field plate, a metal flow field platewith uniform flow channel depth can be produced.

Description

technical field [0001] The invention relates to the technical field of proton exchange membrane fuel cells, in particular to a processing device and method for a metal flow field plate of a proton exchange membrane fuel cell. Background technique [0002] A fuel cell is a power generation device that can efficiently convert fuel and oxidant directly into electrical energy through electrode reactions. Proton exchange membrane fuel cells (PEMFC, Proton exchange membrane fuel cells) are fuel cells with solid proton exchange membrane as electrolyte, hydrogen or methanol as fuel, and air or oxygen as oxidant. The core of PEMFC is membrane MEA and bipolar plate. Membrane MEA is the place of electrochemical reaction, and bipolar plate realizes uniform gas distribution, current collection and drainage. In order to distribute gas and collect current, bipolar plates usually need to have good electrical conductivity, thermal conductivity, resistance to fuel and oxidant penetration, an...
