国产质子交换膜燃料电池关键材料及部件的电池组性能

Investigation on Proton Exchange Membrane Fuel Cell Stacks of Domestic Key Materials and Components

基于质子交换膜燃料电池(Proton exchange membrane fuel cell,PEMFC)技术的实际应用要求,针对其国产关键材料和部件(包括电催化剂、质子交换膜、炭纸、双极板)进行性能表征、电池组制造工艺开发和电池组应用性能研究,结果表明:国产炭纸、复合质子交换膜、复合催化剂以及薄型不锈钢双极板无论是在基本性能还是在电池组应用方面都达到了国外同类产品的水平,能够满足车用燃料电池发动机的要求。目前,复合质子交换膜产品已实现批量生产,炭纸和复合催化剂已具备批量制造能力,薄型不锈钢双极板的批量制造工艺和设备已进入开发阶段,采用这些国产材料和部件组装的PEMFC车用发动机正在进行实际应用考核。初步预计:通过这些国产关键材料和部件的应用,可以将PEMFC的材料成本降低50%以上,同时还可以大幅度提高电池性能,为推进我国燃料电池产品的实际应用奠定基础。

According to the technical and application demands of the proton exchange membrane fuel cell （PEMFC）,the key materials and components,including the catalyst,composite proton exchange membrane,carbon paper,and bipolar plate,are characterized and stack developed.The results show that these materials and components attain the technical level of the import products and suffice for fuel cell vehicle technologies.Presently,the composite proton exchange membrane is mass produced,the capability of mass production of carbon paper and catalyst is also ready,and mass production process and equipment for thin stainless steel bipolar plate has entered development phase.The performance assessment of these materials and components in PEMFC vehicle engine is being implemented.According to the preliminary estimate,the application of these materials and components will reduce the cost of PEMFC stacks by about 50% and improve the performance,which lays the foundation for promoting the practical application of domestic fuel cell products.
