Norwegian researchers have made significant advancements in hydrogen fuel cell technology by developing a new catalyst and membrane that could revolutionize the industry. Despite the efficiency of fuel cells running on hydrogen, their high cost has hindered their widespread adoption. The researchers at SINTEF focused on reducing the platinum content in the catalyst and slimming down the membrane to make fuel cells cheaper and more environmentally friendly. The new catalyst technology involves arranging microscopic platinum particles to strike a balance between material usage and electricity production, resulting in a 62.5% reduction in platinum content. This not only cuts costs but also considers the global challenges of material supply and sustainability. Furthermore, the researchers succeeded in slimming down the membrane by 33%, making it significantly lighter and less expensive. By reducing toxic emissions from harmful substances like PFAS found in current membranes, the new membrane technology is also more environmentally friendly. Despite being razor-thin, the new membrane's performance was not compromised, showcasing its effectiveness and potential for practical implementation in clean energy technologies. The research findings indicate a possible 20% reduction in membrane costs and a 33% decrease in harmful PFAS content. Overall, the innovation holds promise for making future clean energy technologies, such as powerful PEM fuel cells, more affordable and sustainable.
