Palladium, Pd

As the global push for decarbonization accelerates, hydrogen emerges as a key clean energy solution. In particular, green hydrogen—produced without carbon emissions—is gaining momentum as a sustainable alternative to fossil fuels. Central to this technology are platinum group metals (PGMs) such as iridium (Ir), platinum (Pt), and ruthenium (Ru), which serve as essential catalyst materials in hydrogen production, storage, and utilization.


Iridium and Platinum: Strategic Metals for Electrolysis and Fuel Cells

Iridium plays a pivotal role in the oxygen evolution reaction (OER) during proton exchange membrane (PEM) water electrolysis. Its excellent corrosion resistance and electrochemical stability under harsh conditions make it indispensable in green hydrogen production. However, iridium is one of the rarest metals in the Earth's crust, prompting the development of advanced nanocatalyst technologies that minimize usage while maintaining performance.

Platinum is vital for fuel cells that generate electricity through hydrogen oxidation. Known for its high conductivity, thermal resistance, and durability, platinum ensures stable output and long life for fuel cell systems—particularly polymer electrolyte membrane fuel cells (PEMFCs) used in hydrogen vehicles.

Palladium (Pd), another important PGM, complements platinum with its strong hydrogen absorption and release capabilities, often applied in hydrogen storage alloys and catalytic converters.


Cost Reduction, Recycling, and Technology Development Are Essential

Despite their performance advantages, PGMs are expensive and subject to supply risks. This makes efficient recycling and cost-saving innovations crucial. Technologies like single-atom catalysts, metal nanoclusters, and complex oxides are emerging as solutions that lower material costs while retaining catalytic efficiency.

For example, nano-dispersed platinum or iridium mixed with other metals can significantly enhance catalytic activity and reduce PGM load. These innovations help ease economic burdens and support the commercialization of hydrogen energy systems.

Dong-A Special Metals, Inc. specializes in advanced PGM recycling technologies, recovering iridium, platinum, and palladium from spent catalysts and hydrogen-related components. Our recycled catalyst materials meet industry specifications and help shorten lead times, reduce imports, and stabilize domestic supply chains.

As the hydrogen economy advances, demand for high-performance catalyst materials is expected to soar. The strategic importance of PGMs like iridium and platinum will continue, but proactive recycling systems, localization of supply, and innovative catalyst development will determine national competitiveness.

If your company is involved in hydrogen production, fuel cells, or catalyst systems, Dong-A Special Metals is ready to assist with reliable supply solutions. Contact us today for your strategic material needs.
