Johnson Matthey (JM) announced the successful demonstration of its new HyRefine technology for recycling H₂ fuel cell and electrolyzer materials. While there are established routes to recycle the platinum group metals (PGMs), often the ionomer is not recovered. The company believes this is the first ever demonstration of circularity for the PGMs and valuable ionomer together.

JM researchers have proven at lab scale that both the PGMs and the ionomer can be recovered and recycled into new catalyst coated membranes, the performance-defining components at the heart of H₂ fuel cells and electrolysers. Separate experiments have confirmed that the recycled PGM catalysts match the performance of fresh material.

As the H₂ economy takes off, embedding circularity is critical to conserve precious resources and minimize the environmental impact of manufacturing new H₂ technologies. Using a purely chemical process, JM’s HyRefine technology offers efficiency and sustainability benefits compared to conventional PGM refining.

Processing only fuel cell and electrolyzer material, JM’s bespoke HyRefine technology provides additional traceability of the critical PGMs. The output from this process would be 100% secondary (recycled).

Secondary metal has up to a 98% lower carbon footprint than primary (mined) metal, offering significant sustainability benefits. The PGM can then be seamlessly integrated into JM’s PGM catalyst manufacturing and subsequent CCM manufacturing. Following successful 5 liter lab scale demonstrations, JM is now scaling up this technology to run 50 liter pilot trials in its facility in Brimsdown, UK.

Alastair Judge, JM’s Chief Executive, Platinum Group Metals Services said, “This demonstration of our HyRefine technology is a key step on our path to providing a circular service for our fuel cells and electrolyzer customers in the future.

“It’s a fantastic example of how we can leverage our foundational PGM ecosystem, world-leading recycling capabilities and decades of expertise in H₂ technologies and apply this to embed circularity into the H₂ economy.”
