基于专利数据的氢燃料电池电堆技术发展态势分析
Analysis on development trend of hydrogen fuel cell stack technology based on patent data
电堆是氢燃料电池的核心部分。围绕氢燃料电池电堆技术最新专利情况,从专利申请公开、技术来源地、重点研发方向等方面整体分析了电池电堆全球技术发展态势,进一步对电池电堆的核心部件——膜电极技术的最新进展进行研究。分析结果表明,我国是氢燃料电池电堆领域专利的主要创新策源地和目标市场国家;在膜电极、双极板相关技术领域处于领先地位,但在制造工艺、电堆设计和制造与国际水平还有差距;当前膜电极技术分支下低成本、高性能的催化剂技术是备受关注的研发方向。基于此,提出氢燃料电池电堆领域技术创新与专利布局建议。
The stack is the core part of hydrogen fuel cell.This article focuses on the latest patents for hydrogen fuel cell stack technology,and analyzes comprehensively the global cell stack technology development trend from the aspects of patent application disclosure,technology source,and key research and development directions.It further analyzes the latest progress on the technologies for membrane electrode,the core component of cell stack.The analysis results show that China is the main innovation source and target market country for patents in the field of hydrogen fuel cell stacks.China occupies a leading position in the technical fields of membrane electrodes and bipolar plates,but falls behind the international advanced level in the manufacturing process,as well as the design and manufacturing of hydrogen fuel cell stacks.The low-cost high-performance catalyst technology under the current membrane electrode technology branch is a highlight research and development direction that has attracted much attention.Based on this,suggestions are given on technological innovation and patent layout in the field of cell stacks.
