Description

For the fuel battery cathode with proton exchange film structure of in-situ Raman spectrum test and survey Method for testing
Technical field
The present invention relates to the catalytic mechanism of fuel cell field, more particularly to fuel battery cathode with proton exchange film catalyst Research field.
Background technology
Proton Exchange Membrane Fuel Cells（PEMFC：Proton Exchange Membrane Fuel Cell）Technology is electricity One of key technology of electrical automobile development in science and technology, the oxygen reduction reaction of its negative electrode is the weight for restricting fuel cell system power generation performance Want factor.At present usually using cathod catalyst of the noble metal platinum as low-temperature fuel cell, but scarcity of resources due to platinum and It is expensive to limit the practical of low-temperature fuel cell, therefore the non-platinum catalyst of exploitation high efficiency, low cost turns into domestic external combustion Expect the focus and difficult point [1] of battery technology research.
Realize to the in situ study of catalytic reaction that being one of catalytic field in recent years important grinds using in-situ testing technique Study carefully trend, by the research of catalytic reaction, understand chemical state, electronic structure and the geometrical factor and electrochemical reaction of catalyst Relation between activity, so as to be pointed the direction to synthesize new catalyst, realizes the MOLECULE DESIGN of catalyst；Situ catalytic is anti-simultaneously The process and mechanism that should be tested also for PEMFC electrode reactions under solution actual motion condition provide evidence, so as to promote PEMFC The raising of performance.For example, using Situ Mossbauer Spectroscopy measuring technology can be with real-time monitored to during cyclic voltammetry How variation of valence [2] occurs for catalyst, and the technology also observes number to confirm that the reason for catalyst activity fails provides According to [3].For another example, catalyticing research is carried out using In-situ XAFS, in structure, the table of the unsaturated ferrimagnetic structure catalyst of surface coordination Levy and application study aspect gets along with [4 ~ 6].
In-situ Raman spectrum of use starts from the seventies in the research of catalytic field, and in load metal oxide, molecule Abundant achievement [7 ~ 9] is achieved in the research such as the reaction in-situ of sieve and absorption.Compared to other in-situ testing techniques, in-situ Raman Spectral signal can preferably reflect absorption behavior of the species on electrode, and electro-catalysis effect is influenceed by each factor can be rapid More intuitively reflect again, there is its distinctive feature in numerous research electro-catalytic process：1）Catalyst can be provided The structural information of species on itself and surface, this is understanding catalyst and the mostly important information of catalytic reaction；2）Draw original position Graceful spectrum is easier to realize under in-situ condition（High temperature, high pressure, complex system）Catalyticing research, and to catalyst under in-situ condition Carry out the Main way that sign is current catalyst characterization；3）In-situ Raman spectrum can realize grinding in real time from aqueous phase to solid phase Study carefully, this is that many other measuring technologies are difficult to.Application of the Raman spectrum in catalyticing research is except with above-mentioned obvious Feature and advantage outside, also have the advantages that compared with its infrared spectrum for belonging to molecular spectroscopy techniques very prominent:1）It is red External spectrum typically hardly results in lower wave number（200cm-1Below）Spectrum, but Raman spectrum can even obtain tens wave numbers Spectrum.And lower wave number spectral regions reflection catalyst structure information, especially the different structure such as molecular sieve can be in lower wave number spectral regions Show；2）Due to common carrier (such as γ-A12O3And SiO2Deng) raman scattering cross section very little, therefore carrier is negative to surface The interference of the Raman spectrum of loading kind is seldom；And most of carrier (such as γ-A12O3、TiO2And SiO2Deng) in the infrared of lower wave number Absorb very strong, in 1000 cm-1Infrared light is hardly passed through below；3）Because the Raman scattering of water is very weak, therefore in-situ Raman ratio The infrared research for being more suitable for carrying out aqueous phase system.
As can be seen here, the catalytic reaction for in-situ Raman technology being applied into fuel battery cathode with proton exchange film catalyst is ground The development studied carefully to fuel-cell catalyst is significant.But, traditional proton exchange membrane fuel cell structure is by electricity Catalyst/electrode diffusion layer material, amberplex and bipolar plates provided with flow field are constituted, its catalytic reaction occur in electrode and The phase reaction area that amberplex is constituted --- membrane electrode (MEA：Membrane Electrode Assembly).Tradition Electrode diffusion layer material in fuel cell structure causes the hot spot of Raman spectrum can not focus on MEA surface, so that can not Realize that the in-situ Raman test of fuel cell catalyst course of reaction is characterized.
