Tracy HyNi – Sensitive trace gas detection for hydrogen and nitrogen

Scientists of the Heinrich-Heine-University developed a rugged low-cost gas detector. The concept of detection based on the specific light emission of compounds excited electronically by an electric arc. The detection enables a wide range of measurments starting from pure gases down to gas traces (<1 ppm). Signals are achieved in tenths of seconds. At present, the invention is primarily concerned with monitoring operational states of fuel cells and appearing degradation processes in MEAs by detecting either nitrogen in the hydrogen flow or hydrogen within the cathode flow field. Granted US Patent und EP patent application, DE application for hydrogen detection. On behalf of the Heinrich-Heine-University of Düsseldorf, PROvendis offers interested companies the opportunity to obtain a licence for using the presented technology or for continuing the development of the method.
