Fuel cells have been receiving a lot of attention in the scientific domain as one of the most promising alternative energy sources. When applying fuel cell technology to both the grid and automobiles, one issue is persistent: cost. Researchers at Argonne National Laboratory (ANNL) have been looking for a way to combat the price issues. Now, a team of researchers led by ECS member Di-Jia Liu have found a potential way to utilize fuel cells without the high cost of development and commercialization.
A New Catalyst
The team’s development revolves around the notion of using naturally abundant materials without sacrificing efficiency. Current, fuel cells work off a platinum catalyst, which is both expensive and scarce. The new catalyst eliminates the need for the precious material, all while demonstrating performance rates comparable to that of a platinum catalyst.
The scientists developed the new catalyst via the synthesis of a highly efficient, nanofibrous non-precious metal catalyst. If this technique proves to be commercially viable, it transition into automotive technology and extend the range of electric vehicles and potentially eliminate the need for charging.
