摘要
膜电极是质子交换膜燃料电池的核心部件,低铂载量、长寿命的膜电极对于加速其商业化进程具有重要的意义,经过两代技术演化,最新一代有序化膜电极是当前研究热点。以专利技术为视角,基于Himmpat数据库检索结果,分析了有序化膜电极专利申请态势,对比了专利主要来源国和重要申请人情况,重点从催化剂层有序结构、交换膜层或扩散层为基础的全有序结构等技术方向分析了专利技术研究进展。研究发现,从产业化角度,交换膜或扩散层为基础的全有序化结构更有优势,建议国内重点申请人优化专利布局完整性,并在专利转化运用过程中加强对具备一体化生产能力膜电极组件企业的关注。
Abstract
Membrane electrode is the core component of proton exchange membrane fuel cell,and low Pt loading and long-life membrane electrode is very important to accelerate its commercialization.After two generations of technology evolution,the latest generation of ordered membrane electrodes is the current research hotspot.From the perspective of patent technology,based on the search results of Himmpat Database,the patent application situation of ordered membrane electrode was analyzed,and the main countries of origin of the patents and the important applicants were compared.From the directions of the ordered structure of catalyst layer,and the fully ordered structure based on exchange membrane layer or diffusion layer,the research progress of patented technology was also summarized and analyzed.It was found that,from the perspective of industrialization,the fully ordered structure based on exchange membrane or diffusion layer offered more advantageous.It was recommended that the key domestic applicants should optimize the completeness of the patent layout and pay more attention to the membrane electrode module enterprises with integrated production capacity during the process of patent transformation and application.
