Technology Expertise

The research group uses a laboratory for new thermal energy technologies which is equipped for testing and diagnostics of membrane fuel cells and electrolyzers as well as a prof. Radica lab for thermal machines. Equipment includes:

Fuel cell test station for single cells (Teledyne / Medusa) equipped with controllable load and frequency response analysis (Scribner & Associates)

Internal combustion engine test stand (cylinder pressure indicator and exhaust emission measurement)

A complete hydrogen power system (consisting of an electrolyzer, a water tank, a fuel cell, a control load, and a data management and storage system) connected to photovoltaic panels and a wind turbine installed on the roof of the building.
