| Popis: | 107 This study explores the current state of technology development of hydrogen energy by means of patent analysis. Conducting a related hydrogen energy search for the U.S. Patent and Trademark Office patent database, the patent indicators include the number of patents over the years, citations, research and development capabilities and technology life cycle, etc., the analysis includes patent number analysis, country analysis, company analysis, inventor analysis, IPC (International Patent Classification) and UPC (US Patent Classification) analysis. Hydrogen energy patents have a relatively large number of outputs in the past two decades, of which the United States leads the countries with overwhelming number of patents. United Technologies Corporation and GM Global Technology Operations, Inc. have relatively good performance in the enterprise. The IPC technology field focuses on H01M 8/00, and the UPC technology field focuses on 429/017. The results of this research will provide relevant reference to hydrogen energy industry and government as a reference for energy technology and innovation development. |
