- The study's findings could lead to the design of highly-efficient non-noble metal-based cathodes for commercial PEM applications, bridging the gap from lab to factory.
- This research represents a significant advancement in HER catalyst technology, promising a more affordable and sustainable method for hydrogen fuel production.
The hydrogen evolution reaction (HER) is a crucial process for producing clean hydrogen fuel, offering a solution to the climate change crisis. Researchers at Tohoku University recently published findings in Advanced Energy Materials demonstrating a surface reconstruction pathway for non-noble metal-based cathodes, enhancing HER efficiency. By using transition metal phosphides (TMPs) as catalysts, the team achieved durable and cost-effective results, bridging the gap between lab-scale experiments and commercial production. The F modified CoP cathode showed improved activity through surface reconstruction, maintaining high performance for over 300 hours and costing $2.17 per kgH2-1. This development brings the cost of hydrogen production close to the US Department of Energy's target, making it a significant step towards affordable fuel production. The research not only focused on enhancing HER efficiency but also aimed to design realistic options for commercial PEM applications, emphasizing the practical implications of their work.
