Abstract
The demand for hydrogen, which is considered an environmentally friendly energy source, is increasing, and at the same time, the fuel cell market is increasing continuously. This study aimed to establish a strategy for securing intellectual property rights on fuel cell by-product utilization technology for operating expenditure reduction of hydrogen-powered residential buildings. In this patent analysis, this study investigated Korean, American, Japanese, and European patents filed/published/registered by October 2019 and established a technical classification system and classification criteria through expert discussion. To reduce the operating expenditure of hydrogen-powered residential buildings, intellectual property rights will be improved using systems and methodologies involving cathode-side purified air, product water, and oxygen-depleted air captured with the dead-end mode operation of polymer electrolyte fuel cells.
