Dutch Institute for Fundamental Energy Research (DIFFER)

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.

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

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.

Joint research initiative to develop a device that absorbs water vapor from humid air and uses direct solar energy to split it into hydrogen and oxygen. The project includes a feasibility study phase with prototype development and planned optimization phases.

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.
