Peel off the solidification glue with low deflation.Sealant section is a kind of semicircle, and semicircle sealant root is contacted with sealing trench bottom
Length is longer, increases viscous viscous force.And have the smaller i.e. dispensing amount of volume less, realize the purpose of save the cost.
Be equipped with preferably, the membrane electrode assembly includes membrane electrode, between the membrane electrode and hydrogen fuel cell with
Membrane electrode is in integrated catalytic plate.
Preferably, the catalytic plate includes catalysis plate body, the catalysis plate body is equipped with and hydrogen fuel cell phase
The position-limited edge moulding that inlaid type is fixedly connected, be equipped in the position-limited edge moulding it is several be equally uniformly distributed arrangement and with
Hydrogen fuel cell is engaged embedding battery installation card slot.
Preferably, the battery installation card slot is in oval shape structure.
Preferably, form sealed adhesive slot in the sealing baffle, the sealed adhesive slot bottom end be equipped with it is several with it is close
Block plate is in integrated slot bottom flange strap.Slot bottom flange strap increases the contact area with sealant, increases viscous viscous force.
Preferably, the slot bottom flange strap is serrated.Improve the firmness and compactness of sealing fixed structure.
Preferably, the elastic slice sliver transvers section is V-shaped.Elastic slice item plays effective and quick part sealing baffle and leads
Flowing plate mutually securely inlay card connection.
The utility model can reach following effect:
The utility model provides a kind of hydrogen fuel cell deflector sealing structure, compared with prior art, has knot
Structure is simple, production cost is low, easy processing assembly, sealing effect is good, pollution-free, noiseless, high efficiency and spy with long service life
Point.The air-tightness of hydrogen fuel cell is improved, while preventing gas leakage in fuel.Realize extruding force and dispensing amount more preferably
Match, has reached the sealing for preferably realizing hydrogen fuel cell.
