The study focuses on the importance of controlling carbon emissions to combat climate change, highlighting fuel cell technologies as a key solution. By integrating a PEMFC system with hydrogen production from coalbed methane and biomass gasification, the research evaluates four scenarios considering carbon capture. Life cycle assessment and carbon footprint evaluation are used to analyze the environmental impact and carbon emissions of the proposed system. Results show that biomass gasification has a lower environmental impact than coalbed methane, especially during the construction phase. The usage phase was identified as the primary source of carbon emissions, suggesting room for improvement in fuel cell efficiency. Optimizing fuel cell components and utilizing biomass resources for hydrogen production are recommended strategies for enhancing carbon efficiency. The study underscores the potential of hydrogen energy in achieving low-carbon or zero-carbon energy goals, emphasizing the need for sustainable energy sources in the face of depleting fossil fuel reserves. The research also highlights the significance of life cycle assessment in evaluating environmental implications and the importance of minimizing waste and pollution in industrial systems for sustainable development.
