Honeywell has developed new catalyst-coated membrane (CCMs) technology for green hydrogen production and will further test the technology with electrolyzer manufacturers. The new technology focuses on CCMs for PEM electrolyzers and AEM electrolyzers.

Honeywell’s latest CCMs have been shown in lab testing to enable higher electrolyzer efficiency and higher electric current density enabled by a breakthrough proprietary high ionic conductivity membrane and high activity catalyst. This is projected to provide a 25% reduction in electrolyzer stack cost¹.

Honeywell’s green hydrogen program leverages decades of R&D and manufacturing experience in developing and manufacturing market-leading membranes and catalysts for gas processing, refining, steel, and petrochemical industries, as well as the experience in the most recent development of novel membranes for battery and power applications.

“Honeywell is a proven leader in developing innovative membrane technologies, and our latest technology has been validated in lab tests by third-party hydrogen electrolyzer technologists,” said Ben Owens, VP and General Manager, Honeywell Sustainable Technology Solutions. “By accelerating the development of these high-performance CCMs, Honeywell is contributing to the transition to a hydrogen-based economy.”
