本研究以書目計量法探討1991年至2010年燃料電池領域科學與技術的發展，研究對象分別為WOS資料庫及美國USPTO專利資料庫所收錄之20,758篇期刊論文及8,112篇專利。本研究發現在整體趨勢方面，燃料電池領域論文與專利均呈現顯著的成長趨勢，且論文的成長速度較快；在國家分析方面，燃料電池領域的論文與專利高度集中在少數國家，論文數高的國家往往專利數也高。在機構分析方面，論文數高的機構與專利數高的機構少有重複，且兩者的機構類型亦不相同；而在個人分析方面，論文數高的個人與專利數高的個人重複性更低，顯示個人難以兼具論文及專利的高產量。

The study utilizes bibliometrics to explore papers and patents in the field of fuel cell to examine the scientific and technical development in the area. The research data were retrieved from the WOS database and USPTO patent data from the period between 1991 and 2010, which consists of 20,758 papers and 8,112 patents. The authors analyzed numbers of papers and patents to examine the trends in the papers and patents in different countries, organizations and individuals. The results indicate upward growth in both papers and patents in fuel cell, with a higher growth rate for papers. The study shows that major paper and patent output are concentrated in a small number of countries. An imbalance exists between the number of papers published and the patents granted in organizations. The organizations that published papers and patents vary in type and category. Very few individual researchers are able to produce high numbers of both papers and patents.
