Solutions for green hydrogen PEM electrolysis
Proton exchange membrane (PEM) water electrolysis represents a highly promising means of green hydrogen production. However, PEM electrolyzers are expensive, typically requiring costly iridium-based catalysts. Scalable, cost-effective PEM electrolysis to compete with hydrogen produced via steam methane reforming has long remained out of reach.
You can reduce costs in your PEM electrolyzers with the help of the 3M™ Nanostructured Iridium Catalyst Powder E570. We can help you reduce iridium loading and lower system costs, allowing you to meet electrolyzer efficiency and lifetime requirements.
With support from the U.S. Department of Energy, 3M has developed this catalyst to help you overcome barriers to scale in your PEM electrolysis and spearhead the expansion of green hydrogen production.

Fluid handling solutions for alkaline electrolysis
Alkaline electrolysis is about precision. Temperature, flow rates and electrolyte concentration must be controlled to maximize efficiency, manage costs and make green hydrogen from alkaline electrolysis economically viable. This requires alkaline electrolyzers with reliable and precise fluid handling systems.
3M provides custom-engineered technical ceramic components used in a range of fluid handling applications. 3M™ Silicon Carbide Sliding Bearings combine tribological performance under high load with excellent corrosion and wear resistance. They are compatible with various process fluids — including aggressive acids and alkalis — and are used in industrial and process pump applications for hermetically sealed centrifugal pumps and stirrers.
Technical ceramic parts from 3M include seals, bearings and other fluid handling components that can be customized to your application requirements. Contact us to learn more.

The potential of solid oxide electrolysis
Solid oxide electrolysis is expected to play a major role in the clean energy transition. Solid oxide electrolyzer cells have potential to be more energy efficient than PEM or alkaline electrolyzers, helping enable cost-effective, low-carbon hydrogen production. They are ideal for nuclear-powered hydrogen production (pink hydrogen) and other applications in which waste heat can be harvested.
However, roadblocks remain before solid oxide electrolysis can reach commercial viability. Solid oxide electrolyzers operate at high temperatures up to 1,000 °C, increasing mechanical and chemical degradation and limiting electrolyzer lifetime. Managing thermal stress while controlling costs is a fundamental challenge of solid oxide electrolyzer design.
Energy leaders worldwide have used 3M™ Nextel™ Ceramic Fibers and Textiles in solid oxide fuel cells to help maintain stack integrity and extend cell life. Nextel fibers can withstand extreme temperatures and thermal cycling, and 3M is exploring potential applications in solid oxide electrolyzers. Contact us to learn more.
PEM electrolysis by the numbers
Under typical industry operating conditions, every 5 grams of 3M™ Nanostructured Iridium Catalyst Powder E570 could help you produce up to 10 tons of hydrogen per year via PEM water electrolysis. This is made possible by a catalyst areal loading of 0.25 milligrams of iridium per square centimeter (mg-Ir/cm²) or lower - significantly less than the 1 mg-Ir/cm² requirement of other catalysts.
Under laboratory testing, a loading of 0.25 mg-Ir/cm² meets representative industry durability requirements with decay rates less than 7 mV per 1000 hours at current densities up to 5 A/cm² and an operating temperature of 80°C.
