Did you know2023
Johnson Matthey is the only company in the world that invented the dominant emissions control technology for internal combustion engines (automotive THREE-way catalyst, 1973) AND is a leading developer of the dominant emissions-free alternative (PEM hydrogen fuel cell catalyst). JM's Clean Air division manufactures the platinum-palladium-rhodium catalysts that make gasoline ICE vehicle exhaust meet EPA and Euro 6 emission standards — serving the existing global vehicle fleet of 1.4+ billion ICE vehicles. JM's Hydrogen Technologies division develops platinum-based PEM fuel cell electrode catalysts and iridium oxide-based PEM electrolyzer catalysts — serving the hydrogen vehicle and green hydrogen electrolysis market. The same London precious metals company: improving the ICE vehicle that will be replaced by the hydrogen/electric vehicle AND building the catalyst technology for the replacement vehicle AND the electrolyzer that will make the green hydrogen to fuel it. JM publishes the PGM Market Report — an annual analysis of global platinum and palladium supply and demand — making it simultaneously the largest automotive catalyst technology company AND the most authoritative public information source on the metals its own technology consumes.
