Resumen:
Una universidad alemana ha desarrollado un detector de gas robusto y de bajo coste que permite realizar medidas de gases puros y gases traza (<1 ppm). El concepto de detección se basa en la emisión específica de luz de compuestos excitados electrónicamente mediante un arco eléctrico. La tecnología se utiliza actualmente para monitorizar estados operativos de pilas de combustible y procesos de degradación en ensambles membrana-electrodo detectando nitrógeno en el flujo de hidrógeno o hidrógeno dentro del campo de flujo del cátodo. La separación espectral de la señal de hidrógeno y las señales de nitrógeno de las señales que acompañan se realiza mediante filtros ópticos. La universidad busca socios con el fin de establecer acuerdos de licencia y cooperación técnica.

Tittle:
Trace gas detection for hydrogen and nitrogen.
Summary:
A German university has developed a rugged low-cost gas detector. The detector enables a wide range of measurements starting from pure gases down to gas traces (<1 ppm). The university offers a license agreement as well as a technical cooperation agreement.
Description:
Scientists of a German university developed a rugged low-cost gas detector. The concept of detection is based on the specific light emission of compounds excited electronically by an electric arc. The detection enables a wide range of measurements starting from pure gases down to gas traces (<1 ppm). Signals are achieved in tenths of seconds. The detector is always available for recording signals since a recreation time for the measuring system is not required. The setup can operate in harsh environments and is for instance insensitive against chosen temperatures, temperature changes or the degree of humidity.

At present, the invention is primarily concerned with monitoring operational states of fuel cells and appearing degradation processes in MEAs (Membrane Electrode Assemblies) by detecting either nitrogen in the hydrogen flow or hydrogen within the cathode flow field. Spectral separation of the hydrogen signal and the nitrogen signals from accompanying signals is simply carried out by optical filters.

The method provides the opportunity to measure a variety of different gases and can therefore be considered as a tool to inspect and pursue technical processes in which gases are involved. This is easily realized by inserting properly selected optical filters or substituting optical filters by a mini-spectrograph.

The university offers a license agreement as well as a technical cooperation agreement to companies that are interested in using and further developing the invention for other applications.
Advantages and Innovations:
Unlike the current proceedings this methodology allows the detection of N2 or H2 in trace concentrations (<1 ppm). Other advantages of this invention are:
- Simultaneous detection of compounds in mixed gases
- Rugged system
- Unaffected by climatic conditions, temperatures and humidity
- Control of fuel cells and biogas plants
- Controlling the purity level of hydrogen
