Abstract—Fuel cell is an environment-friendly renewable energy source. Major countries that are trying to diversify their power supply are expanding their technology development and efforts to spread the usage of fuel cell. In this study, the level of usage in each country was analyzed through technology competitiveness analysis on fuel cell. To analyze technology competitiveness, total four elements of influence, competitiveness, activity, and open innovation were considered. Influence was calculated using forward citation of applied patent, and competitiveness was calculated using the number of patent family. For open innovation, joint application network between countries was settled and analysis was made through degree centrality. In the result, besides MCFC field, USA was found to be the most competitive, while Japan and Korea were found to be relatively less competitive. When it was studied by a major element, USA had a high level of competitiveness and open innovation, and Canada had high level of influence.
