Es handelt sich hierbei um eine:The invention relates to a measuring, control, regulating and monitoring unit for the reliable operation of a fuel cell system. It is a:

Vorrichtung und Verfahren zur Messung, Steuerung, Regelung und Überwachung eines Brennstoffzellensy-stems, welches mit Hilfe von Brennstoff und Oxidator chemische Energie in elektrische Energie umwandelt, dadurch gekennzeichnet, dass die zum Betrieb des Brennstoffzellensystems wichtigen Hauptparameter von einer zentralen Mess-, Steuer-, Regel- und Überwachungseinheit erfasst werden und die daraus resultierenden wichtigen Zufiihrungsparameter aktiv gesteuert, geregelt und überwacht sowie die übrigen brennstoffzellen- und/oder lastspezifischen Nebenparameter an untergeordnete Mess-, Steuer-, Regel- und Überwachungseinheiten weitergeleitet werden.Device and method for measuring, controlling, regulating and monitoring a fuel cell system which converts chemical energy into electrical energy with the aid of fuel and oxidizer, characterized in that the main parameters important for the operation of the fuel cell system are provided by a central measuring, control, Control and monitoring unit are detected and the resulting important Zufiihrungsungsparameter actively controlled, regulated and monitored and the other fuel cell and / or load-specific secondary parameters are forwarded to subordinate measuring, control, and monitoring units.

Stand der TechnikState of the art

Brennstoffzellen wandeln chemische Energie in elektrische Energie um, indem ein Brennstoff, vornehmlich Wasserstoff ensprechende, und ein Oxidator, vornehmlich Luftsauerstoff, eine Elektronenaustauschreaktion an einer Membran durchführen. Brennstoffzellenpatente gibt es zum Beispiel von J. Eberspächer GmbH & Co. KG als Europäisches Patent mit der Nummer EP 1 906 478 Al. Derzeit werden Brennstoffzellensysteme mit fest vorgegebenen Betriebsparametem betrieben. Diese Vorgehensweise ist zum Beispiel in der Offenlegungsschrift DE 101 27 600 Al vom Deutschen Zentrum für Luft- Raumfahrt e.V. zu sehen. Die Parameter des Brennstoffzellensystems sind in diesem Fall für Volllast eingestellt und fuhren daher bei einer geringeren Last zu einer Verringerung des Wirkungsgrades sowie zu einer Verkürzung der Lebensdauer der Brennstoffzelle.Fuel cells convert chemical energy into electrical energy by having a fuel, primarily hydrogen, and an oxidizer, primarily atmospheric oxygen, perform an electron exchange reaction on a membrane. Fuel cell patents are available, for example, from J. Eberspächer GmbH & Co. KG as European Patent No. EP 1 906 478 A1. Currently fuel cell systems are operated with fixed operating parameters. This procedure can be seen, for example, in the published patent application DE 101 27 600 A1 from the German Aerospace Center e.V. The parameters of the fuel cell system are set in this case for full load and therefore run at a lower load to a reduction in the efficiency and to shorten the life of the fuel cell.

Aufgabenstellungtask

Es ist die Aufgabe dieser Erfindung, eine Vorrichtung und ein Verfahren zu entwickeln, die die Betriebsparameter je nach Lastbereich des Brennstoffzellensystems steuert bzw. regelt. Durch eine aktive Regelung wird die Brennstoffzelle in jedem Betriebszustand immer unter optimalen Bedingungen betrieben. Dieses aktive Regelungsverfahren hat, besonders auf die Lebensdauer der Brennstoffzelle, positive Auswirkungen. Außerdem sollen durch den Einsatz eines Hauptmikrocontrollers, der die Hauptparameter erfasst und die wichtigsten Zuführungsparameter selbst regelt, ein optimaler Betrieb der Brennstoffzelle in allen möglichen Lastfällen gewährleistet werden. Mit Hifie von nachgeordneten Mikrocontrollem sollen die übrigen Parameter des Brennstoffzellensystems gesteuert bzw. geregelt werden. Durch das jjositionieren der Mikrocontroller direkt an den zu messenden Signalen soll der Messaufwand und somit auch der Messfehler, welcher durch lange Leitungen entsteht oder durch andere äußere Einwirkungen wie z.B. elektromagnetischen Störungen, verringert werden.It is the object of this invention to develop a device and a method which controls the operating parameters depending on the load range of the fuel cell system. Through an active control, the fuel cell is always operated under optimal conditions in any operating condition. This active control method has positive effects, especially on the lifetime of the fuel cell. In addition, the use of a main microcontroller, which detects the main parameters and regulates the main feed parameters themselves, ensures optimal operation of the fuel cell in all possible load cases. With the help of downstream microcontrollers, the other parameters of the fuel cell system are to be controlled or regulated. By jjositionieren the microcontroller directly to the signals to be measured, the measurement effort and thus the measurement error caused by long lines or by other external influences such. electromagnetic interference, be reduced.
