Solid oxide fuel cell (SOFC) generates electricity through electrochemically converting chemical energy using ammonia as fuel at high temperature. SOFC using ammonia as a fuels can be largely divided into autothermal reforming SOFC (ATR-SOFC) and direct ammonia SOFC (DA-SOFC) systems. The ATR-SOFC system reforms ammonia externally before supplying it to the fuel cell, whereas, DA-SOFC system directly uses ammonia in the fuel cell. This study proposed a new DA-SOFC system and analyzed its energy efficiency, economic feasibility, and environmental impact. The energy efficiency of the DA-SOFC system was improved by approximately 7.27% compared to the ATR-SOFC. In addition, the DA-SOFC system reduced investment costs and CO2 emissions by 35.5% and 96.9% respectively, compared to ATR-SOFC system. This study can provide valuable insights for stakeholders considering distributed power generation using ammonia as fuel and can serve as foundational data for future research.
