Technology Marketing Summary

Argonne scientists have developed a rational design of catalysts for chemical reactions in fuel cells. The approach could lead to a new generation of electrochemical materials for efficient and clean energy conversion. Today, approximately 30 grams of platinum (Pt) are used to catalyze the electrochemical reaction in a fuel cell. At today’s prices, the cost of this amount of Pt catalyst material is almost $1,600. Argonne’s new, improved catalyst materials could dramatically reduce the current cost of fuel cell catalysts because less Pt is required for the electrochemical reaction.

Description

Argonne scientists successfully created the new catalyst materials for polymer electrolyte membrane fuel cells (PEMFCs) that are not only active, but stable over wide potential ranges and operating conditions. Using a “materials-by-design" approach, researchers developed a new multi-metallic catalyst that is highly active and durable for the oxygen-reduction reaction in PEMFCs. Using novel synthetic routes to develop shape-controlled nanoparticles with a metallic core and different metallic shell, Argonne researchers demonstrated that the catalyst nanoparticles possess high catalytic activity comparable to that of Pt-bimetallic alloys—and offers superior durability. The new catalyst exhibits enhanced mass-activity, more than one order of magnitude over Pt bulk catalysts. This discovery sets a new bar for catalytic activity of the cathodic reaction in fuel cells, which will help bring PEMFCs for hydrogen-powered vehicles closer to massive commercialization. Scientists also expect the technology to make overarching contributions to other areas of science well beyond the focus on electrocatalysis.
