Embodiment Construction
[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0019] Such as figure 1 As shown, the present invention includes: an intermediate isolation gasket 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, the anode unipolar plates 2 and cathode unipolar plates 3 have a flow field 12 and a gas channel 13, which are formed by stamping and placed in the middle isolation pad Sheet 1 on both sides. The shape of the hollowed-out part of the central area of the intermediate spacer 1 is consistent with the convex 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 opposite to each other by stamping and protruding, and are positioned by four positioning holes 15 and pressed toge...

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 proton exchange membrane fuel cells. Background technique [0002] Fuel cells have become a new direction for vigorous research in various countries due to their wide application prospects in alternative energy sources for automobile power 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. Cost and quality account for 60% to 80%. In the proton exchange membrane fuel cell, the bipolar plate plays a role in providing the reaction flow field, separating the oxidant and reducing agent, collecting power, and supporting the membrane electrode. Therefore, the bipolar plate must have non-penetration, good electrical conductivity, certain mechanical strength and rigidity. In addition, due to the weak acidity of the reacti...
