Abstract
The invention relates to a method for monitoring and/or regulating fuel cells, in particular comprising determining the composition of the operating gases of the fuel cells. The method comprises the following steps: introducing the gas mixture to be analyzed into a measuring cell (1); producing an arc in the measuring cell (1); absorbing the radiation emitted by the arc; optical filtering of the emitted radiation and/or spectral decomposition of the emitted radiation; converting the emitted radiation into an electric signal; evaluating the electric signal.
Claims12
A method for monitoring and/or regulating fuel cells, the method comprising:
- determining a composition of one or more operating gases of the fuel cells, wherein the step of determining the composition of the one or more operating gases includes the steps:
- introducing a gaseous mixture to be analyzed into a measuring cell;
- creating a light arc in the measuring cell;
- accepting a radiation emitted by the light arc;
- optically filtering of the emitted radiation and/or spectral splitting of the emitted radiation;
- converting the emitted radiation into an electric signal;
- and
- evaluating the electric signal.
A measuring cell to analyze a composition of one or more operating gases of fuel cells, comprising:
- a housing, showing a gas inlet and a gas outlet;
- and
- a discharge chamber, which is connected to the gas inlet and the gas outlet, with the discharge chamber being enclosed by the housing at least partially and in which an electrode and a counter-electrode are arranged with a discharge gap;
- wherein the electrode and the counter-electrode are configured to form a light arc and at least one means being provided to accept an emitted radiation.
