Es sind verschiedene Arten von Brennstoffzellensystemen bekannt, in denen aus hierfür geeigneten Flüssigkeiten auf elektrochemischem Wege Wasserstoff gewonnen wird. Für den mobilen Einsatz im Kraftfahrzeug eignen sich insbesondere Polymer-Elektrolyt-Membran(PEM)-Brennstoffzellensysteme, da diese im Vergleich zu anderen Systemen eine sehr hohe Leistungsdichte aufweisen und daher relativ kompakt ausgeführt sein können. Diese sog. PEM-Brennstoffzellensysteme benötigen zum Betrieb Wasser, das zur Befeuchtung der Kathodenluft eingesetzt wird. Zusätzlich wird Wasser zur Befeuchtung des Wasserstoffes bzw. zur Erzeugung eines wasserstoffreichen Gases (Reformat) durch die Reformierung von Kohlenwasserstoffen (bspw. Benzin) benötigt.It Various types of fuel cell systems are known, in those from this suitable liquids Hydrogen is obtained by electrochemical means. For the mobile Use in motor vehicles are particularly suitable for polymer electrolyte membrane (PEM) fuel cell systems, because they have a very high power density compared to other systems have and therefore can be made relatively compact. These so-called PEM fuel cell systems need to operate water used to humidify the cathode air becomes. additionally is water for humidification of the hydrogen or for production a hydrogen-rich gas (reformate) through the reforming of hydrocarbons (eg gasoline) needed.

Befeuchtung sind bspw. aus der
Das bei den bekannten Systemen eingesetzte Wasser verlässt die Brennstoffzelle in Form von Wasserdampf und wird normalerweise durch einen Gasauslass (Auspuff) an eine Umgebung abgegeben. Für den mobilen Einsatz muss daher zusätzliches Wasser als Betriebsstoff mitgeführt werden, wodurch das Fahrzeuggewicht erhöht und seine potentielle Reichweite eingeschränkt wird.The in the known systems used water leaves the Fuel cell in the form of water vapor and is usually through a gas outlet (exhaust) delivered to an environment. For the mobile Use must therefore additional Water carried as fuel which increases the vehicle weight and its potential range limited becomes.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, ein Brennstoffzellensystem mit einer Befeuchtung mit Wasser oder anderem flüssigem Medium derart weiterzuentwickeln, dass dem System während des Betriebes kein flüssiges Medium außer Kondensat zusätzlich von außen zugeführt werden muss.Of the The present invention is based on the object, a fuel cell system with moistening with water or other liquid medium in such a way, that during the system the operation no liquid Medium except condensate additionally from the outside supplied must become.
Diese Aufgabe wird bei einem Polymer-Elektrolyt-Membran-Brennstoffzellensystem gemäß dem Oberbegriff des Patentanspruchs 1 durch einen in einem Schalldämpferbereich eines Abgasstrangs integrierten Wärmetauscher zur Kühlung der Abgase und zur Kondensierung von darin enthaltenen Wasseranteilen erreicht. Für den mobilen Einsatz ist eine solche Wasserrückgewinnung besonders vorteilhaft, da auf diese Weise ein geschlossener Wasserkreislauf realisiert werden kann. Der Kundennutzen ist durch den Verzicht auf zusätzliches Tanken von Wasser deutlich erhöht. Das Wasser das im Wärmetauscher abgeschieden wird, wird in das PEM-Brennstoffzellensystem zurückgeführt und kann dort wieder zur Befeuchtung und/oder Kühlung der Brennstoffzellen verwendet werden.These Task is in a polymer electrolyte membrane fuel cell system according to the generic term of claim 1 by a in a silencer area an exhaust line integrated heat exchanger for cooling the Exhaust gases and for condensation of water contained therein reached. For mobile use, such water recovery is particularly advantageous because be realized in this way a closed water cycle can. The customer benefit is by waiving additional Refueling of water increased significantly. The water in the heat exchanger is returned, is returned to the PEM fuel cell system and can there again for humidification and / or cooling of the fuel cell be used.
Ein bereits vorhandenes Schalldämpferbauteil ist vorteilhafterweise am Gaseintritt um eine Wärmetauscherzone erweitert. In dieser Wärmetauscherzone wird das Gas weiter abgekühlt und dabei kondensiert Feuchtigkeit. Diese Wärmetauscherzone kann bspw. in Kreuzstrombauweise aus gestapelten Rippenrohrkühlern ausgeführt sein. Als Kühlmedium kann in vorteilhafter Weise Kühlwasser verwendet werden. Strömt das feuchte Abgas in bekannter Weise von oben nach unten durch den Wärmetauscher, wird das Kondensat durch die Schwerkraft und zusätzlich durch die Gasströmung abgeschieden. Diese Wärmetauscherzone kann u.U. selbst schalldämpfend wirken. Aus dem feuchten Abgas wird an den Schalldämpfereinbauten zusätzliches Wasser abgeschieden. Im Schalldämpfer können perforierte Innenböden und Reflexionsrohre vorgesehen sein. Durch die Einbaulage des Bauteils und andere geeignete konstruktive Maßnahmen, z.B. Abscheideinbauten und Lochbleche sammelt sich das Kondensat an bestimmten Stellen des Schalldämpfers und wird dort über eine Entnahmevorrichtung in den Wasservorratsbehälter des Brennstoffzellensystems zurück geführt. Die Montage des Bauteils an durch Fahrtwind gut angeströmter Stelle kann von Vorteil sein. Zusätzlich kann eine Zwangsbelüftung in Form eines Ventilators oder dgl. vorgesehen sein.One already existing silencer component is advantageously expanded at the gas inlet to a heat exchanger zone. In this heat exchanger zone the gas is cooled further and moisture condenses. This heat exchanger zone can, for example. be designed in cross-flow construction of stacked finned tube coolers. As a cooling medium can advantageously cooling water be used. flows the moist exhaust gas in a known manner from top to bottom through the Heat exchanger, is the condensate is separated by gravity and additionally by the gas flow. This heat exchanger zone can u.U. even sound-absorbing Act. From the humid exhaust gas is at the muffler installations additional Water separated. In the muffler can perforated interior floors and reflection tubes may be provided. Due to the installation position of the component and other suitable constructive measures, e.g. Abscheideinbauten and perforated plates, the condensate collects in certain places of the muffler and gets over there a removal device in the water reservoir of the fuel cell system back guided. The assembly of the component to well flowed through by wind can be an advantage. additionally can be forced ventilation be provided in the form of a fan or the like.
