This innovation isn’t just about creating a solution to carbon-free energy. It’s about reimagining energy to be more accessible, efficient, and adaptable across a variety of high-value applications.
Meet Dura.
The first ever low permeability bilayer proton exchange membrane that is durable, chemically impermeable, and conductive that handles and integrates like traditional perfluorosulfonic acid membranes.
Dura uses a composite approach to reduce gas permeation across the membrane while maintaining high conductivity and stability in order to enable thinner membranes with overall lower membrane resistance.
Dura cuts down hydrogen crossover to address the root cause of free radical formation in fuel cells while enhancing electrolyzer safety, especially at high pressures and low current densities.
Meet Electra.
Our advanced electrolyzer membrane maximizes efficiency and current density, dramatically reducing the costs of green hydrogen production, making it a sustainable and economically viable fuel option.
Addressing both PFAS regulation and safety concerns, our thin membranes enable safe high pressure operation while drastically lowering operational and regulatory risks.
We strategically align demand with cost-reducing innovations, paving the way for robust infrastructure development in essential sectors such as shipping and aviation.
Celadyne’s close collaborations with hydrogen producers and users integrate our technology to foster strong partnerships, enabling long-term infrastructure buildout for a thriving hydrogen economy.
