Gas flow controllable even at high temperatures above 800 degrees Celsius
Dresden (pts005/08.04.2013/08:00) – 8. April 2013
The new Laminar Flow Meter from EBZ determines the flow rates of gases even at high temperatures.
The fuel cell processes hydrogen and oxygen into water and generates electrical energy in addition to heat. In the case of the SOFC fuel cell, hydrogen can also be obtained from other gases, such as natural gas, by a reforming process. The purity and the volume ratio of the gases used are particularly decisive for the efficiency and the service life of the fuel cell. Within the framework of the EU funded project ASSENT, the researchers at the EBZ Dresden have developed a system that can precisely control the flow rates of the gases used even at the high temperatures of over 800 degrees Celsius arising in the reforming process.
A sensor consisting of several lamellae measures the amount of gas flowing through and continuously sends the values to the controller. In this way, the amount of hot gases flowing to the fuel cells can be regulated exactly and the new sensor thus prevents over- or under-supply with gases. This leads to a higher efficiency of the SOFC fuel cell and a longer service life.
