Solid-state photoelectrochemical cell prototype

1 mention

A prototype device designed to capture water vapor from humid air and convert it to hydrogen and oxygen using solar energy. The device integrates polymeric electrolyte membranes, porous photoelectrodes, and water-absorbing materials in a membrane-integrated design. The first prototype achieved 70% of the performance of an equivalent water-filled device.

Solid-state photoelectrochemical cell

A device that captures water vapor from ambient air and converts it to hydrogen and oxygen using direct solar energy. The prototype combines polymeric electrolyte membranes, porous photoelectrodes, and water-absorbing materials in a membrane-integrated design.

Polymeric electrolyte membranes

Component of the photoelectrochemical cell that facilitates ion transport during the hydrogen production process.

Porous photoelectrodes

Electrodes with porous structure that capture light and facilitate the electrochemical splitting of water. The current prototype uses UV-absorbing materials that capture less than 5% of available sunlight.
