Abstract
The utility model discloses a fuel cell used anticorrosive structure, in particular to an inside race type anticorrosive structure used by a fuel cell end plate and an acquisition board. The inside race type anticorrosive structure comprises the end plate, an insulating plate, the acquisition board and an inlet; the end plate is connected with the acquisition board through the insulating plate; the inlet is provided with an inside race; and the end plate, the insulating plate and the acquisition board are respectively contacted with the external surface of the inside race; two O-shaped sealing rings are respectively arranged at the two ends of the inside race, and are respectively and hermetically connected with the end plate and the acquisition board; the top part of one end connecting the inside race with the acquisition board is connected with a hydrogen radical plate or an oxygen radical plate. The inside race type anticorrosive structure has the advantages that the structure is simple, the processing is easy, the cost is low, the end plate and the acquisition board can be effectively protected not to be corroded, and the mass production is suitable.
Description
Technical field
The utility model relates to a kind of fuel cell anti-corrosion structure, relates to a kind of fuel cell end plate specifically and adopts the inner cased type anti-corrosion structure that electroplax is used.
Background technology
Proton Exchange Membrane Fuel Cells (Proton Exchange Membrane Fuel Cell, PEMFC) be described as one of preceding 50 years ideal energy presentation mode of 21 century, its advantage shows as energy conversion efficiency height, cleanliness without any pollution, peace and quiet, can start fast at ambient temperature etc.Thereby Proton Exchange Membrane Fuel Cells is expected to become in future the main energy sources in public and private places such as electric automobile, family, movie theatre, hotel, supermarket, becomes fresh combatants mobile, the non-moving energy.Particularly as the main power source of electric motor car, Proton Exchange Membrane Fuel Cells is the first-selected object of countries in the world researcher research direction.But it is the same with other fuel cells, the manufacturing cost of Proton Exchange Membrane Fuel Cells is higher, caused the great difficulty of commercial operations, wherein, end plate, the design of adopting electroplax and bipolar plates and processing charges are to influence Proton Exchange Membrane Fuel Cells cost important factors.The operational environment of Proton Exchange Membrane Fuel Cells is faintly acid, and contains Cl
-, F
-, SO
4 2-Plasma, metallic plate (as stainless steel) had stronger corrosiveness, and fuel gas, oxidant etc. are by end plate, adopt in the manifold feeding flow field of milling quarter on inlet common on the electroplax and the bipolar plates in Proton Exchange Membrane Fuel Cells, its end plates, adopt electroplax and be generally metal material, the bipolar plates material that adopted of Proton Exchange Membrane Fuel Cells mostly is graphite at present.Can imagine,, will cause Proton Exchange Membrane Fuel Cells overall performance and life-span to reduce so if end plate, adopt electroplax and be subjected to sour corrosion, oxide etch.So how to take measures, protect end plate and adopt electroplax and do not corroded extremely important.
The utility model content
The utility model provides a kind of fuel cell anti-corrosion structure, and it is simple in structure, is easy to processing, and cost is low, can effectively protect end plate and adopt electroplax and do not corroded, and is suitable for producing in batches.
The utility model adopts following technical solution:
A kind of fuel cell anti-corrosion structure comprises end plate, insulation board, adopts electroplax, inlet, and end plate and adopting between the electroplax connects with insulation board, and described porch is provided with interior cover, end plate, insulation board, adopts electroplax and contacts with lining the outer surface of respectively; In the two ends of cover be provided with " O " RunddichtringO, respectively with end plate with adopt electroplax and be tightly connected; In cover with adopt the end top that electroplax is connected and be connected with hydrogenous substrate or oxygen substrate.
The cross section of cover is consistent with the cross section of inlet in described, is quadrangle circular, oval or the band fillet.
Cover is the non-metallic material of anti-80 ℃ of following temperature in described, preferred polyformaldehyde or polyvinyl chloride.
The fuel cell anti-corrosion structure that the utility model provides, by interior cover is set, make metal end plate and adopt electroplax and isolate by gas or liquid, and with overlapping two ends in the sealing of " O " RunddichtringO, thereby reach etch-proof purpose, its structure muscle list is easy to processing, cost is low, is suitable for producing in batches; In addition, this non-metallic material as anti-80 ℃ of following temperature of interior cover makes itself also corrosion-resistant, longer service life.
