Tanaka Precious Metal Technologies, a Japanese manufacturer, has been honored with the 2025 Technology Award for their advancements in proton exchange membrane (PEM) water electrolysis. The Catalyst Manufacturers Association, Japan, presented the award in acknowledgment of Tanaka's development and application of electrode catalysts that serve a dual function in PEM water electrolysis. This innovation addresses the challenge of hydrogen crossover by reducing hydrogen concentration on the anode side while maintaining high electrolysis efficiency. PEM water electrolysis, crucial for a carbon neutral society, utilizes solid polymer electrolyte membranes to split water into hydrogen and oxygen efficiently, producing high-purity hydrogen suitable for applications requiring high current densities and rapid response to power fluctuations. Tanaka's recognition by the Catalyst Manufacturers Association highlights their commitment to technological progress in the catalyst industry and the utilization of precious metals. Established in 1885, Tanaka has a longstanding history of providing products supporting various business needs with a focus on precious metals.
