Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] As shown in the accompanying drawings, the thin metal bipolar plate of the proton exchange membrane fuel cell of the present invention consists of an anode flow field plate 10, a cathode flow field plate 20 and a support plate 30, as Picture 1-1 , Figure 1-2 and Figure 1-3 As shown, the flow field form of the anode flow field plate 10 is a single-channel serpentine flow field, and the cross-section of the flow field channel groove as the fuel gas distribution pipe 15 is semicircular with a radius of 0.75 mm. The end of one end of the distribution pipe 15 is a fuel gas inlet 12, and a sealing ring groove 13 is arranged on the periphery of the flow field channel groove. The anode flow field plate 10 is stamped from a stainless steel sheet, and its thickness is 0.1-0.2 mm. After the stainless steel sheet is formed, it is treat...

Abstract

This invention discloses one proton exchange film fuel battery metal double electrode board, which comprises anode flow board, cathode flow field board and two flow field board supportive board, wherein, the flow field type is of single channel of snake flow field and the anode is of semi round shape; the cathode flow board oxidation agent is open groove with section for rectangle shape or round shape; the said two flow field board is impacted by stainless steel board with thickness of 0.1 to 0.2 mm to form good conductive anti-erosion process.

Description

technical field [0001] The invention relates to a component of a proton exchange membrane fuel cell, in particular to a thin metal bipolar plate of a proton exchange membrane fuel cell. Background technique [0002] Proton Exchange Membrane Fuel Cells (PEMFC) use hydrogen and oxygen as raw materials to directly generate electricity, with high energy conversion efficiency (40-60%) and environmental protection. It is an ideal alternative power source for internal combustion engine power plants. It is also an ideal portable power source, home power source and distributed power station. Usually, a proton exchange membrane fuel cell is assembled from several groups of unit cells. Each unit cell in turn consists of a membrane electrode assembly, bipolar plates and sealing elements. The batch manufacturing technology of membrane electrode assemblies and sealing components has matured, but the design and manufacturing technology of bipolar plates is still in development and perfec...
