Technical Name Non-precious metal catalysts driving advancements in natural gas electrolysis and fuel cell technologies
Project Operator National Taiwan University of Science and Technology
Project Host 王丞浩
Summary
This technology enables low-voltage (~1.5 V) electrolysis of natural gas (methane) or hydrogen-enriched mixtures to produce ultra-pure hydrogen, which is directly used in fuel cells. The membrane electrode assembly (MEA), made of a non-precious metal catalyst and ion-exchange membrane, operates in both electrolysis and fuel cells. This dual-function design lowers costs and enhances scalability for real-world applications.
Scientific Breakthrough
Conventional methane decomposition technologies internationally rely heavily on high-energy plasma processes, often accompanied by CO₂ emissions. In contrast, this technology enables methane electrolysis at a low voltage (~1.5 V) without the need for high-energy plasma. Utilizing a membrane electrode assembly (MEA) composed of non-precious metal catalysts, the system offers low cost, high scalability, and zero carbon emissions, demonstrating strong potential for practical development.
Industrial Applicability
This technology is suitable for petrochemical, heavy, electronics, and semiconductor industries. Natural gas can be directly delivered via pipelines to facilities, where it undergoes methane electrolysis to produce high-purity hydrogen. The hydrogen can be used in industrial processes or as a power source via fuel cells. Due to its flexibility, the technology is not limited to specific sectors and can showing great potential for widespread implementation.
