Researchers at the IMDEA Materials Institute in Spain have developed a catalyst that uses 75% less platinum [1] while delivering comparable performance.
The discovery addresses one of the primary economic barriers to the widespread adoption of hydrogen fuel cells. Because platinum is an expensive precious metal, its high cost has historically limited the scalability of hydrogen-powered systems.
The new catalyst maintains a high level of efficiency despite the reduction in precious metal content. According to research data, the catalyst retains 85% of its performance after 150,000 charge-discharge cycles [2]. This durability suggests that the technology could withstand the rigors of long-term industrial or automotive use.
While some reports have described the development as a platinum-free alternative, the verified research indicates that the catalyst still utilizes platinum, just in significantly smaller quantities [1]. The reduction of 75% compared with conventional fuel-cell catalysts [1] represents a substantial shift in material requirements.
Hydrogen fuel cells generate electricity through a chemical reaction between hydrogen and oxygen, with water as the only byproduct. The catalyst is the critical component that accelerates this reaction. By lowering the amount of platinum required, the researchers aim to accelerate the deployment of these systems across various sectors.
The IMDEA Materials Institute team focused on creating a material that does not sacrifice longevity for cost. The ability to maintain 85% performance over 150,000 cycles [2] provides a benchmark for how the material behaves under repeated stress, a key metric for commercial viability.
“The catalyst retains 85% of its performance after 150,000 charge-discharge cycles.”
This development signals a shift toward making hydrogen energy economically competitive with battery-electric alternatives. By reducing dependence on rare and expensive minerals, the industry can lower the entry price for fuel-cell vehicles and stationary power plants, potentially speeding up the transition to zero-emission energy infrastructure.
