摘　　要：[研究目的]为帮助燃料电池相关研究人员和创新主体更好地掌握技术发展趋势及演化路径、把握竞争态势,本研究试图通过技术主路径从专利视角来分析燃料电池的技术演进。[研究方法]由于现有的SPC算法存在一定滞后性,会埋没新申请的专利,因此本文通过构建同族专利引文网络,在SPC算法中引入了时间维度对其进行了改进。并通过人工阅读主路径专利内容,梳理了燃料电池领域的技术演进路径。还着重分析了SOFC和PEMFC这两大技术的发展趋势,从而对燃料电池发展方向进行预测。[研究结论]研究结果表明,对SPC算法的改进均达到了目标效果,并取得了较好的实证结果;系统控制问题和电极问题的设计与优化构成了燃料电池专利的主要内容,并且贯穿燃料电池发展的始终;相比于质子交换膜燃料电池,固体氧化物燃料电池在未来会更有发展潜力和发展前景。[Research purpose]In order to help fuel cell related researchers and innovators understand the technology development trend and evolution path,this study attempts to analyze the evolution of fuel cell technology from the perspective of patents through main path analysis(MPA).[Research method]Since the existing SPC algorithm has a certain lag,which will bury the newly applied patent,this paper introduces a time dimension into the SPC algorithm to improve it.The technology evolution path in fuel cells is sorted out by manually reading the patent content of the main path.The development trend of SOFC and PEMFC technology is also emphatically analyzed,so as to predict the development direction of fuel cells.[Research conclusion]The improvement of the SPC algorithm has reached the target effect and achieved good empirical results.The design and optimization of system control and electrodes constitute the main content of fuel cell patents,and run through the development of fuel cells;in the long run,compared to proton exchange membrane fuel cells,the solid oxide fuel cells have greater development potential and prospects.
