Current proton-exchange membrane (PEM) fuel cells rely on noble metals like platinum for their performance. Pt is a critical raw material making up over 50% of the fuel cell stack cost, but is limited in supply and with a volatile cost. Supply is concentrated in South Africa, Zimbabwe and Russia.
The Celcibus catalyst can lower the cost for the fuel cell stack by up to 30% with a more sustainable footprint. It is based on transition metals, much cheaper than noble metals, in the active sites. While traditional fuel cells require the recovery of noble metals, a process creating poisonous by-products, fuel cells using the Celcibus catalyst can be handled in the regular metal recycling process.
