基于专利的燃料电池及关键技术发展态势研究

Research on Development Trend of Fuel Cell and Key Technologies Based on Patent Analysis

本文从专利数据角度聚焦电动汽车行业,对燃料电池领域的总体发展态势、主要研发机构、技术生命周期、关键分支技术和技术功效等方面进行分析。燃料电池专利技术发展已进八成熟期,日本占据领先地位。我国专利申请量逐年上升,企业应做好专利布局。燃料储备技术短时间内没有较好的技术突破口,我国企业和科研机构可以加大对燃料储备的检测技术和安全性研究。

Focusing on the eleclric vehicle industry, this paper analyzes fuel cell on the overall development trend, major R＆D institutions, technology life cycle, the key branches of technology, and technology efficiency, based on patent data. With fuel cell technology matured, Japan has taken a leading position. China Patent applications increased year by year and our enterprises should be prepared to patent layout. There is no better technical breakthrough in the short time of fuel reserves technology. So our enterprises and research institutions can improve the detection technology and safety research on fuel reserve.
