Description
Technical field
The present invention relates to a kind of preparation method of core component of used in proton exchange membrane fuel cell.
Background technology
Proton Exchange Membrane Fuel Cells (PEMFC) has high power density; high-energy conversion efficiency; cold-starting; advantages of environment protection; promise to be most the power source of zero disposal of pollutants electric car; make it in today that global energy crisis and environment go from bad to worse, become one of focus of international new and high technology competition.The core component of used in proton exchange membrane fuel cell (catalyst coated membrane, CCM) then be that development in recent years gets up to be different from conventional film electrode (membraneelectrode assembly, MEA) core components of PEMFC of structure.Traditional membrane electrode (MEA) manufacture method mainly is catalyst to be transferred to form Catalytic Layer on the diffusion layer, then with proton exchange membrane hot pressing, floods on its Catalytic Layer or spraying proton conductive resin solution again.The kind electrode structure, Catalytic Layer combines relatively poor with proton exchange membrane, and a very important shortcoming is that the proton conductive resin of dipping or spraying is merely able to enter Catalytic Layer surface and does not arrive Catalytic Layer inside, and proton-conducting is subjected to very big the influence.And employing CCM technology (catalyst is directly transferred on the proton exchange membrane), Catalytic Layer combines with film closely, and Catalytic Layer and film can be done very thinly, and proton-conducting is very good, not only improve the electrochemical reaction activity of Catalytic Layer, but also can reduce the manufacturing cost of membrane electrode.
[US6074692, US5330860, US5316871, US5211984, US5234777, JP2002280003] described a kind of catalyst pulp with configuration and directly printed, is coated with and be sprayed on the method for preparing CCM on the proton exchange membrane.[JP5538934, JP5847471] described a kind of method that Pt directly is deposited on the film surface.These above-mentioned method technologies are simple, and catalyst loss is little, but the swelling set of film is bigger in the catalyst transfer process.[US6749892, EP1137090A2] described a kind of method of electric arc sputter that adopts catalyst metals or carbon supported catalyst has been splashed to the method that the proton exchange membrane surface forms CCM.Catalyst metals is directly transferred to the CCM on the proton exchange membrane, because the very high surface activity of nano metal particles, catalyst generally exists with the form of reunion or film, and this has just reduced the surface activity area of catalyst.CN1269428A has introduced a kind of powder direct heat with catalyst and protonically conductive polymer and has been pressed onto the method for preparing CCM on the proton exchange membrane.The CCM of this method preparation, its Catalytic Layer is comparatively fine and close, but continuity and uniformity are bad, and the fuel cell output performance is also bad.
[US5415888, US5702755, US4272353, US3134697, US6391486B1] introduced a kind of with the configuration catalyst slurry at first print, cast or be sprayed on the materials such as polyester film, PTFE film, porous dielectric film, sheet metal, glass plate, solvent is removed in heating, catalyst is transferred to the method for preparing CCM on the proton exchange membrane by hot pressing then.Because just removing, so proton exchange membrane do not have the swelling phenomenon to solvent before Catalytic Layer is transferred to proton exchange membrane, Catalytic Layer has good uniformity.[US5211984, US5234777] adopts Nafion is proton conductive substance and binding agent, uses transfer printing to prepare CCM.The CCM of this method preparation, Catalytic Layer contacts with the proton exchange film close, and uniformity is better, but the hydrophilic and hydrophobic of its Catalytic Layer is unadjustable.For improving the hydrophobicity of Catalytic Layer, US5272017 adds PTFE (polytetrafluoroethylene) in catalyst pulp.Though this method can be improved the hydrophobicity of Catalytic Layer, PTFE can not disperse in Catalytic Layer continuously uniformly, thereby lacks the modulability in fuel cells applications upper hose reason.
The employed core component of existing Proton Exchange Membrane Fuel Cells (CCM), Catalytic Layer generally use hydrophilic proton conductive resin or hydrophobic polytetrafluoroethylene (PTFE) as binding agent; When only adopting proton conductive resin as binding agent, the Catalytic Layer that makes combines with film closely, and Catalytic Layer can be done very thinly, and proton-conducting is very good, but this CCM hydrophily is too strong, is difficult to water management regulated make the Catalytic Layer water blockoff easily and battery performance sharply descends; When only adopting polytetrafluoroethylene (PTFE is generally emulsion) as binding agent, Catalytic Layer has excellent hydrophobic property, but the proton conductivity of Catalytic Layer is significantly less than the Catalytic Layer of employing protonically conductive polymer as binding agent.
Summary of the invention
