Aoki Lab
Machine-translated · View original
A lab developing solid-state electrochemical devices that produce fuel from water and air.
AboutAbout the lab
Fuel synthesis from water and air with solid-state devices.
The Aoki Lab aims to synthesize energy carriers from water and air.
To this end, the lab develops inorganic materials that generate interstitial hydrogen with fluctuating charge, along with electrochemical devices that use these materials.
Through this work, the lab aims to contribute to decarbonization on a global scale.
Key terms
- Energy carrier
- A substance that can store and transport energy, such as hydrogen or ammonia
- Electrochemical device
- A device that converts between electricity and chemical reactions, such as a fuel cell or a water electrolyzer
- Interstitial hydrogen
- Hydrogen that has entered the gaps between the atoms arranged in a crystal

*Illustrative imageElectrolysis that produces hydrogen from water vapor
The lab is developing a method to efficiently produce hydrogen from water vapor, using a new electrolysis cell that uses both hydrogen ions (H⁺) and hydride ions (H⁻). The aim is to create an energy source that supports a decarbonized society.
*Illustrative imageA fuel cell that generates power directly from ammonia
Ammonia is a fuel that stores hydrogen in a form that is easy to transport. The lab studies the mechanism of a fuel cell that uses an alloy permeable only to hydrogen as an electrode and generates power with ammonia directly as fuel.
