The Reversible Fuel Cell

.
Cipher Neutron is redefining the future of energy with the world’s first patent-pending Reversible Fuel Cell (RFC) that utilizes Graphene Slurry to store green hydrogen in a non-compressed, safe, and scalable form. This groundbreaking innovation merges hydrogen production and power generation into a single, integrated system — delivering a level of flexibility, efficiency, and safety that conventional electrolysers, fuel cells, and batteries cannot match.
At the core of this technology is the use of Graphene Slurry as a storage medium, enabling hydrogen to be captured and stored as protons (H⁺ ions) in a liquid phase rather than as high-pressure gas. This method eliminates the need for complex, energy-intensive compression systems, significantly reducing storage costs, safety risks, and infrastructure requirements. As a result, Cipher Neutron’s RFC system functions not only as a green hydrogen generator (Electrolysis Mode – E-Mode) but also as a power-producing unit (Fuel Cell Mode – FC-Mode) — seamlessly switching between production and supply of clean electricity.
Often referred to as a “Hydrogen Battery,” the Reversible Fuel Cell introduces a radically new approach to long-duration energy storage. It provides zero self-discharge, operates without flammable gas tanks, and is well-suited for residential, industrial, and remote applications that require reliable, clean, and autonomous power solutions.
Cipher Neutron is actively leading the charge toward commercializing this transformative technology, with plans to deploy RFC systems across both residential and industrial sectors. By coupling the breakthrough capabilities of Graphene-based storage with the dual functionality of a reversible fuel cell, Cipher Neutron is setting a new global standard in how we produce, store, and use clean energy.
The future of energy is flexible, safe, and emission-free — and Cipher Neutron is building it.

RFC vs Conventional Systems

Cipher Neutron’s Reversible Fuel Cell (RFC) represents a transformative leap in energy technology. Traditional hydrogen systems rely on multiple separate components — including electrolysers, compressors, storage tanks, and fuel cells — each adding cost, complexity, and inefficiencies to the overall system. In contrast, the Cipher Neutron RFC consolidates all of these functions into a single, integrated unit, dramatically simplifying deployment and operation.
At the core of this innovation is our patent-pending Graphene Slurry, which stores hydrogen in a non-compressed ionic form. This eliminates the dangers and costs associated with high-pressure gas storage while improving safety, reducing system footprint, and minimizing energy loss during the storage and release process.
With a projected round-trip efficiency of 45–55%, Cipher Neutron’s RFC offers a far more effective solution than conventional systems, which often suffer significant energy losses due to compression and transfer. The RFC is modular, scalable, and zero-emission, making it ideal for a wide range of applications—from residential energy storage and microgrids to remote infrastructure and industrial backup power.
Designed with safety, simplicity, and sustainability at its core, the Cipher Neutron RFC is more than just a technological advancement — it’s a platform for a cleaner, more flexible energy future.
