Pajarito Powder Releases Engineered Electrolyzer Catalyst (EEC)

Iridium Oxide electrolyzer catalyst performance

May 14, 2018

Pajarito Powder’s newly released Engineered Electrolyzer Catalysts (EEC) provide a notable improvement in electrolyzer efficiency and performance. New publicly available data recently released on the performance of two specific products reflects advancements made in catalysts materials and progress toward major cost reductions.

Pajarito Powder manufactures high-performance electrolyzer catalysts explicitly designed for Proton Exchange Membrane (PEM), AEM, and alkaline systems. These products consist of PGM, supported-PGM, and PGM-free catalysts available in 10 g to 1 kg batch-levels. High quality production platinum black and pre-production iridium oxide products explicitly designed for electrochemical applications
are available with electrochemical-relevant specifications.
