Embodiment Construction

[0018] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, the present invention includes: an intermediate spacer 1 , an anode unipolar plate 2 , a cathode unipolar plate 3 , a first sealing gasket 4 , and a second sealing gasket 5 . Two symmetrical integral metal anode unipolar plates 2 and cathode unipolar plates 3, anode unipolar plates 2 and cathode unipolar plates 3 have a flow field 12 and a gas guide channel 13, which are formed by stamping and placed in the middle isolation pad slice 1 on both sides. The shape of the hollowed out part in the central area of ​​the intermediate spacer 1 is consistent with the raised areas of the anode unipolar plate 2 and the cathode unipolar plate 3 . The anode unipolar plate 2 and the cathode unipolar plate 3 are stamped and protruding on one side facing each other, positioned with four positioning holes 15, and pressed toget...

Abstract

The present invention refers to combined type integral bipolar plate for hydrion exchange membrane fuel cell of fuel cell technology field. Said invention includes five sheets and gaskets, which are intermediate isolating gasket, two monopole boards, two sealing gaskets, wherein two monopole boards respectively located upper and lower sides of intermediate isolating gasket, two sheet gaskets respectively adhered on monopole board surface. All sheets and gaskets have same edge contour size, being rectangle with four square openings on both sides edge, respectively used as hydrogen fuel inlet, outlet, oxygen inlet and outlet, cooling fluid and outlet set nearing the hydrogen fuel outlet and oxygen outlet, round locating hole set at four corners of sheet and gasket.

Description

technical field [0001] The invention relates to a bipolar plate in the technical field of fuel cells, in particular to a combined integral bipolar plate for a proton exchange membrane fuel cell. Background technique [0002] Fuel cells have become a new direction of vigorous research in various countries due to their wide application prospects in automobile power alternative energy and mobile energy. The bipolar plate is the core component of the fuel cell, accounting for 80% of the total weight of the stack and more than 30% of the total cost, and both cost and quality account for 60% to 80%. In a proton exchange membrane fuel cell, the bipolar plate serves to provide a reaction flow field, separate oxidants and reductants, collect power, and support membrane electrodes. Therefore, it is required that the bipolar plate must have non-penetrating properties, good electrical conductivity, certain mechanical strength and rigidity and other properties. Due to the weak acidity ...
