The installations the group has manufactured include a wind tunnel capable of characterising several flow geometries of open-cathode fuel-cell plates or a variety of ventilation systems by analysing the load loss and flow rate. This is a very useful tool for dimensioning the operating conditions of cooling systems in the open-cathode fuel cells. The wind tunnel is made of PVC with a well-known geometry and it has outlets for placing pitot tubes to measure flow and load loss or other measurement systems, such as column gauges or sensors.
