Diverting from conventional reinforcement of PFAS‑free membranes, Coreionix membranes with durable technology reduces swelling by 30–40%, improving dimensional stability and interfacial integrity. They maintain acceptable power density compared with other membranes, enabling drop‑in use in existing fuel cell and electrolyzer stacks. Lower swelling and greater robustness reduce cracking, delamination, and gas crossover, directly enhancing durability. An extended lifetime reduces the stack replacement frequency and lowers the levelized costs of hydrogen and electricity over the system’s life. PFAS‑free design also addresses regulatory and environmental concerns related to persistent fluorinated chemicals, thereby improving sustainability. Together, these features make durable‑technology PFAS‑free membranes a stable, high‑performance, and environmentally responsible choice for next‑generation energy systems. 

Coreionix durable membrane technology powers our next-generation PEM and AEM electrolyzers, turning renewable electricity and water into high-purity green hydrogen and oxygen with exceptional efficiency and durability.

 In PEM mode, the coreionix proton-conducting membrane drives proton transport in an acidic environment for compact, high-pressure operation, while in AEM mode, an anion-selective coreionix membrane transports hydroxide ions under alkaline conditions, enabling the use of existing catalysts and cost-effective system materials.

 Across both platforms, our durable membranes provide mechanical strength, chemical stability, and reduced gas crossover, ensuring reliable long-term performance for industrial, mobility, and grid-scale hydrogen applications. 

Our durability-enhanced PEM and AEM fuel cells create a unified membrane platform for clean hydrogen energy in mobility and stationary applications. 

In heavy trucks and buses, they deliver excellent durability against vibrations and temperature shifts, supporting real drive cycles with fast acceleration and braking. Their low crossover and gas separation maintain efficiency and reduce maintenance costs. For stationary use, they scale reliably for buildings, microgrids, data centers, and industry, with long membrane life and stable output under cyclic operation. PEM systems excel in high-power, fast-response scenarios such as grid support, while AEM designs use non-precious catalysts to enable cost-effective solutions. Both leverage Coreionix membranes for compact, modular systems producing electricity, heat, and water with near-zero emissions, and they are ideal for decarbonizing transport and energy infrastructure.
