Norwegian researchers at SINTEF, an independent research institute, have achieved a breakthrough in hydrogen fuel cell technology by developing ultra-thin components that significantly reduce production costs and environmental impact. The team focused on two critical elements: the membrane and the platinum catalyst, which together account for 41% of a fuel cell's cost. By reducing the membrane thickness by 33%, they not only lowered material expenses by 20% but also minimized the use of PFAS, a persistent pollutant. Additionally, the researchers optimized the arrangement of platinum particles, slashing platinum content by over 62% without compromising energy output. "By reducing the amount of platinum in the fuel cell, we're not only helping to reduce costs, we're also taking into account the global challenges regarding the supply of important raw materials and sustainability," said researcher Patrick Fortin. Hydrogen fuel cells, which convert hydrogen into electricity with only water and heat as byproducts, are already powering superyachts, ships, and helicopters. However, their high cost has limited widespread adoption. The Norwegian team's innovations could pave the way for broader use in transportation, a sector responsible for nearly 30% of U.S. greenhouse gas emissions. If scaled, the technology could replace combustion engines, reducing harmful tailpipe emissions and improving public health. The research aligns with global efforts to make hydrogen fuel cells a viable alternative to fossil fuels, particularly in industries where battery-electric solutions are less practical. Fortin emphasized the potential impact: "If the innovations are put into practice, our research will contribute to making future clean energy technologies cheaper and more sustainable."
