Refers to a layer of material ranging in thickness from fractions of a nanometer to several micrometers. In this context, it applies to the construction of the fuel cell membrane.

Advanced imaging technique to be used in the laboratory to study catalysts in action at high magnification.

The primary focus of the laboratory is investigating and developing heterogeneous catalyst systems for renewable energy applications and climate-neutral processes.

A state-of-the-art research facility established through a cooperation agreement between Humboldt Universität and Helmholtz-Zentrum Berlin to investigate and develop heterogeneous catalyst systems for renewable energy technologies and climate-neutral economy applications.

Research project investigating the effects of elevated operating pressures (1-10 bar) on photoelectrochemical cell efficiency for hydrogen production. The study combined experimental work with multiphysics modelling to optimize bubble dynamics and overall performance.

Computational model developed by HZB researchers to simulate and predict photoelectrochemical cell behavior under various pressure conditions, accounting for bubble dynamics, light scattering, and electrochemical reactions.

Devices that use light-powered electrodes to split water into hydrogen and oxygen. Current best-performing versions achieve up to 19% energy conversion efficiency. The HZB research demonstrates that operating at 8 bar can improve efficiency by 5-10%.
