基于多源数据对氢燃料电池不同创新环节的知识关联关系进行深入研究,描摹了技术驱动创新发展的演变过程。以2000—2023年全球主要资金项目(探索研究)、国际会议(前沿研究)、期刊论文(基础研究)、发明专利(应用研发)等公开科技文献数据为基础,对氢燃料电池研发技术体系和关键技术进行了梳理与研究,结果表明,未来氢燃料电池关键技术竞争高地主要集中在催化剂、双极板等关键材料与技术方向,其中催化剂以高活性、高稳定性、低成本、纳米协同材料、失活抑制、功能化元素等为重点研发方向;双极板以低成本材料、轻量化材料、关键涂层材料等为重点研发方向。

Based on multi-source data,the knowledge correlation relationship between different innovation stages of hydrogen fuel cell is deeply researched,and the evolution process of technology driven innovation development is described.Based on publicly available scientific and technological document data such as major global funding projects (exploratory research),international conferences (frontier research),journal papers (basic research),and invention patents (application research) from 2000—2023,the research and development technology system and key technologies for hydrogen fuel cell have been sorted and studied.It is found that the key technologies for hydrogen fuel cell in the future will mainly compete in catalyst,bipolar plate and other key materials and technology directions.The research and development direction for catalysts will focus on high activity,high stability,low cost,nano collaborative materials,deactivation inhibition,and functionalized elements.The research and development direction for bipolar plate will focus on low-cost materials,lightweight materials and key coating materials.
