MIT engineers have made significant progress in the development of proton conductors that could revolutionize clean energy technologies. Proton-conducting materials are crucial for various applications like fuel cells and electrolyzers, which play a vital role in producing clean electricity and fuels such as hydrogen. Current inorganic materials require high temperatures for efficient proton conduction, leading to energy consumption and material degradation. The MIT team identified key traits that enable fast proton conduction and discovered six new materials with promising conductivity through simulations and database screenings. These materials show potential for outperforming existing options, offering opportunities for advancements in fuel cells, electrolyzers, proton batteries, and computing devices. The research not only unveils potential new materials but also enhances the understanding of proton conduction mechanisms at the atomic level. The findings, detailed in the journal Energy and Environmental Sciences, highlight the importance of developing efficient proton conductors for tackling global climate change and advancing clean energy technologies. While practical applications may take time to materialize, the research paves the way for a more sustainable and environmentally friendly future.
