| 1 | The Controllable Design of Catalyst Inks to Enhance PEMFC Performance:A Review显示文摘Typical catalyst inks in proton exchange membrane fuel cells(PEMFCs)are composed of a catalyst,its support,an ionomer and a solvent and are used with solution processing approaches to manufacture conventional catalyst layers(CLs).Because of this,catalyst ink formulation and deposition processes are closely related to CL structure and performance.However,catalyst inks with ideal rheology and optimized electrochemical performances remain lacking in the large-scale application of PEMFCs.To address this,this review will summarize current progress in the formulation,characterization,modeling and deposition of catalyst inks.In addition,this review will highlight recent advancements in catalyst ink materials and discuss corresponding complex interactions.This review will also present various catalyst ink dispersion methods with insights into their stability and introduce the application of small-angle scattering and cryogenic transmission electron microscopy(cryo-TEM)technologies in the characterization of catalyst ink microstructures.Finally,recent studies in the kinetic modeling and deposition of catalyst inks will be analyzed. | Yuqing Guo Fengwen Pan Wenmiao Chen Zhiqiang Ding Daijun Yang Bing Li Pingwen Ming Cunman Zhang | 2021 | Electrochemical Energy Reviews2021，4，1： | 2 |

| 6 | Study on carbon matrix composite bipolar plates with balance of conductivity and flexural strength显示文摘In order to balance the conductivity and flexural strength of graphite composite bipolar plates,the influence of conductive filler on the properties of graphite composite bipolar plate was comprehensively studied by using phenolic resin as binder,natural flake graphite as conductive substrate and functional carbon materials with different structures as auxiliary filler.The results show that the particle size of conductive substrate has an important influence on the conductivity enhancement of auxiliary filler.The influence of conductive particle size on auxiliary filler electrical conductivity improvement was first investigated in this research.The effects of various auxiliary filler concentrations on improving electrical conductivity and flexural strength were then examined.This research has substantial implications for the balance of electrical conductivity and flexural strength of graphite composite bipolar plates. | Junsheng Zheng Yuhang Peng Runlin Fan Jing Chen Zize Zhan Dongmei Yao Pingwen Ming | 2023 | Chinese Chemical Letters2023，34，5： | 1 |

| 8 | Accelerated Test of Silicone Rubbers Exposing to PEMFC environment显示文摘The durability of sealing material is one of the major challenges to the overall lifetime of proton exchange membrane fuel cell(PEMFC).In order to study the failure mode and aging mechanism of fuel cell seals,this paper focuses on the most widely used commercial silicone rubber,and an ex-situ accelerated aging method was employed by simulating the circumstance of PEMFC,including higher temperature and clamping force,lower p H value and F-with higher concentration.The main factors that affect the performance of the seal were obtained through the test of their morphologies and mechanical properties.The failure mode of the aging mechanism of the rubbers were analyzed through scanning electron microscopy(SEM),energy dispersive spectrometer(EDS),attenuated-total-reflection infrared spectroscopy(ATR-IR),mass loss,compression set(CS),etc.It was found that temperature played an important role in the deterioration of seal performance,and the change of the parameters of the compression set with time conformed the dynamic empirical formula,which provides the experimental basis for the lifetime prediction of the seals. | Daijun Yang Jingwen Ma Qing Zhang Bing Li Pingwen Ming Cunman Zhang | 2020 | Progress in Natural Science:Materials International2020，30，6： | 0 |
| 9 | Pt‑Based Intermetallic Compound Catalysts for the Oxygen Reduction Reaction:Structural Control at the Atomic Scale to Achieve a Win–Win Situation Between Catalytic Activity and Stability显示文摘The development of ordered Pt-based intermetallic compounds is an effective way to optimize the electronic characteristics of Pt and its disordered alloys,inhibit the loss of transition metal elements,and prepare fuel cell catalysts with high activity and long-term durability for the oxygen reduction reaction(ORR).This paper reviews the structure–activity characteristics,research advances,problems,and improvements in Pt-based intermetallic compound fuel cell catalysts for the ORR.First,the structural characteristics and performance advantages of Pt-based intermetallic compounds are analyzed and explained.Second,starting with 3d transition metals such as Fe,Co,and Ni,whose research achievements are common,the preparation process and properties of Pt-based intermetallic compound catalysts for the ORR are introduced in detail according to element types.Third,in view of preparation problems,improvements in the preparation processes of Pt-based intermetallic compounds are also summarized in regard to four aspects:coating to control the crystal size,doping to promote ordering transformation,constructing a“Pt skin”to improve performance,and anchoring and confinement to enhance the interaction between the crystal and support.Finally,by analyzing the research status of Pt-based intermetallic compound catalysts for the ORR,prospective research directions are suggested. | Jue Wang Fengwen Pan Wenmiao Chen Bing Li Daijun Yang Pingwen Ming Xuezhe Wei Cunman Zhang | 2023 | Electrochemical Energy Reviews2023，6，1： | 0 |
| 10 | Modifying Carbon Supports of Catalyst for the Oxygen Reduction Reaction in Vehicle PEMFCs显示文摘For current carbon-supported Pt catalysts in vehicle proton exchange membrane fuel cells(PEMFCs),the insufficient stability and durability of carbon supports are severe limitations under operating conditions.This paper adopts the accelerated stress test(AST)method to study the carbon corrosion of catalysts,which is significant to efficiently select the catalysts supports in fuel cells.Graphitized carbon blacks with various surface properties are heated under different conditions,followed by evaluation of their antioxidation capacity with the AST.It is shown that optimally graphitized carbon blacks demonstrate superior stability,retaining a constant quinone/hydroquinone(QH)transition peak potential for over 70,000 AST cycles.A Pt catalyst supported on the selected graphitized carbon exhibits excellent durability at both the rotating disk electrode(RDE)and membrane electrode assembly(MEA)levels.The final specific mass activity(MA)of the optimum catalyst is 47.87 mA/mgPt,which is 2.06 times that of commercial Pt/C(23.31 mA/mgPt)in the RDE tests.The final maximum power density of the optimum catalyst is 525.68 mW/cm^(2),which is 305.52 mW/cm^(2)higher than that of commercial Pt/C after undergoing the AST during the MEA measurements.These results prove that the rational surface features of carbon supports play a vital role in improving the overall fuel cell performance by realizing uniform dispersion of Pt nanoparticles,resisting corrosion,and reinforcing metal-support interactions. | Qiong Xue Daijun Yang Lei Jiang Bing Li Pingwen Ming | 2021 | Automotive Innovation2021，4，2： | 0 |
