Domesticmembraneplatform for critical defenseandindustrial systems
Our membrane solves the chokepoint of every electrochemical system. It enables 5x fuel cell durability, 7x electrolyzer current density, and 80% less iridium — and we make it in America.
Security and sovereignty are now industrial policy
The Russian invasion of Ukraine spiked natural-gas-derived hydrogen from $1.50 to $6.70 per kilogram. Iranian pressure on the Strait of Hormuz doubled ammonia prices to $800 per tonne. Critical material supply chains are being rerouted around China. The next decade of defense and industrial competitiveness depends on owning the enabling layers domestically — and the membrane is one of those layers.
One membrane. Defense and industry today. Every electrochemical system tomorrow.
Celadyne's multi-layer proton exchange membrane is in fuel cells and electrolyzers today, with applications across flow batteries, electrochemical separation, and electrochemical compression on the platform roadmap. The same membrane that goes into a Navy submarine oxygen generator goes into a fuel cell for truck, ship, and data center power.
The membrane hasn't meaningfully changed since 1994. We rebuilt it.
Our low permeability bilayer proton exchange membrane reduces hydrogen crossover by over 50%, addressing the root cause of fuel cell and electrolyzer failure.
Our ultra-thin low permeability proton exchange membrane for electrolyzers improves both safety and efficiency, especially at high pressures and low current densities.
Join our exclusive 2025 initiative to co-create electrolyzer solutions for steel, concrete, defense, and energy infrastructure. Collaborate with us to build technology tailored to your needs.
Paving the way to a profitable carbon-free future
Enabling low carbon intensity products
The purchase orders for low carbon steel, low carbon shipping, and low carbon chemicals are in. The company that can supply that will create a differentiated product, grow, and take the global market.
Addressing 50% of Global Emissions
Starting with defense and trucking and expanding to shipping, rail, agriculture, grid power, and industrial heat, addressing 50% of global emissions.
