Abstract
Description
Die folgende Erfindung beschreibt eine vorteilhafte Anordnung von einzelnen Brennstoffzellenmodulen in einem Gesamtsystem.The The following invention describes an advantageous arrangement of individual Fuel cell modules in an overall system.
Hintergrund der Erfindungbackground the invention
PEM (Polymer-Elektrolyt-Membran)-Brennstoffzellen benötigen für den Betrieb ein Oxidationsmittel, üblicherweise Sauerstoff, der in der Mehrzahl der Anwendungen der natürlichen Umgebungsluft entnommen wird. Dabei stellt sich die Frage der Zuführung der Luft zu den Reaktionszonen im Innern der Brennstoffzelle. Bei geschlossenen Systemen wird die Frischluft üblicherweise durch eine Membranpumpe bzw. einen Kompressor der Brennstoffzelle zugeführt. In mancher Hinsicht (z.B. bzgl. einer möglicherweise erforderlichen Konditionierung (Befeuchtung, ggf. Temperierung) der Luft) bietet ein System mit einer geschlossenen Kathode gewisse Vorteile, für manche Anwendungen bzw. Brennstoffzellengestaltungen ist dies jedoch nicht erforderlich, so daß der (meist erhebliche) elektrische Energiebedarf dieser peripheren Komponenten durch Wahl eines Brennstoffzellenstacks mit offener Kathode deutlich reduziert werden kann, so daß der Systemwirkungsgrad insgesamt höher ausfällt.PEM (Polymer electrolyte membrane) fuel cells require for operation an oxidizing agent, usually Oxygen, which in the majority of applications of the natural Ambient air is removed. This raises the question of the supply of Air to the reaction zones inside the fuel cell. When closed Systems, the fresh air is usually by a diaphragm pump or a compressor of the fuel cell fed. In some respects (e.g., one that may be required Conditioning (humidification, possibly temperature control) of the air) offers a system with a closed cathode has certain advantages, for some However, this is not applications or fuel cell designs required, so that the (usually considerable) electrical energy requirements of these peripheral components by choosing a fuel cell stack with open cathode clearly can be reduced so that the Overall system efficiency higher fails.
Für die Zuführung der Frischluft bei einem System mit offener Kathode werden üblicherweise auf die entsprechende Seitenfläche des Stacks kleine Ventilatoren/Gebläse aufgesetzt, die die Frischluft zwangsweise dem Stack zuführen bzw. die Luft durch die offene Kathode des Stacks ansaugen. Häufig ist jedoch die Förderleistung dieser Gebläse bei Betrieb mit Nennspannung viel größer als für den Luftbedarf des jeweiligen Stacks erforderlich, so daß entweder mit Hilfe zusätzlicher Steuerungs- bzw. Regelungstechnik die Drehzahl der Gebläse dem aktuellen Luftbedarf des Stacks angepaßt werden muß bzw. die Gebläse überdimensioniert sind.For the supply of Fresh air in an open cathode system is usually on the corresponding side surface of the stack small fans / blower mounted, which forced the fresh air to the stack or suck in the air through the open cathode of the stack. Frequently, however the delivery rate this fan when operating at nominal voltage much larger than for the air requirement of the respective Stacks required, so that either with Help additional Control technology the speed of the fans the current Air requirement of the stack adapted must be or the blowers oversized are.
