Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Erzeugung von elektrischer Energie gemäß dem Oberbegriff des Patentanspruches 1.The The invention relates to a device for generating electrical Energy according to the preamble of claim 1.
Aus
der
Ein wesentlicher Nachteil dieser Erfindung ist die verhältnismäßig aufwendige Montage, was unter anderem durch die hohe Anzahl an benötigten Bauteilen verursacht wird.One a major disadvantage of this invention is the relative complex assembly, which among other things by the high number of required components is caused.
Weiterhin weist die Vorrichtung ein unnötig hohes Gewicht auf. Dies ist vor allem bei tragbaren und mobilen Anwendungsgebieten nachteilig. Auch für Anwendungen im Automobilbereich ist ein niedriges Gewicht erforderlich, da ein hohes Gewicht einen hohen Verbrauch an Betriebsstoffen zur Folge hat.Farther the device has an unnecessarily heavy weight. This is particularly disadvantageous in portable and mobile application areas. Also for applications in the automotive sector is a low Weight required as high weight high consumption to operating materials.
Darüber hinaus weist die Vorrichtung ein hohes Bauvolumen auf, was den Platzbedarf der Vorrichtung unnötig erhöht, und damit den Einsatzzweck einschränkt.About that In addition, the device has a high volume, what the space requirement unnecessarily increased the device, and thus the Restricts purpose.
Es ist Aufgabe der vorliegenden Erfindung, die eingangs beschriebene Vorrichtung derart weiterzubilden, dass diese ein geringeres Bauvolumen und ein geringes Gewicht aufweist.It is the object of the present invention, which is described above Further develop device such that it has a smaller volume and has a low weight.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.These The object is solved by the features of claim 1.
Die erfindungsgemäße Vorrichtung zur Erzeugung von elektrischer Energie, welche einen Brennstoffzellenstapel und eine Leistungselektronik aufweist, sieht vor, dass wenigstens eine der Endplatten des Brennstoffzellenstapels auf wenigstens einer Seite über den Brennstoffzellenstapel hinaus verlängert ist, und der Brennstoffzellenstapel und die Leistungselektronik durch die wenigstens eine verlängerte Endplatte verbunden sind.The Inventive device for the production of electrical energy containing a fuel cell stack and a Power electronics, provides that at least one of End plates of the fuel cell stack on at least one side over the fuel cell stack is extended out, and the Fuel cell stack and the power electronics by at least an extended end plate are connected.
Da durch die verlängerte Endplatte die Funktion einer Gehäuseplatte übernommen wird, können eine oder mehrere der Gehäuseplatten durch eine oder mehrere der Endplatten ersetzt werden. Dadurch wird die Anzahl der benötigten Bauteile, die Herstellungskosten, sowie das Gewicht verringert und der Montageaufwand der Vorrichtung vereinfacht. Durch den Entfall von Gehäusedurchführungen und Dichtungen, kann die Vorrichtung einfacher abgedichtet werden.There taken over the function of a housing plate by the extended end plate can, one or more of the housing plates be replaced by one or more of the end plates. This will the number of components required, the manufacturing costs, and reduces the weight and the assembly cost of the device simplified. Due to the omission of housing feedthroughs and seals, the device can be sealed more easily.
Die Erfindung sieht vor, dass der Brennstoffzellenstapel und die Leistungselektronik über wenigstens eine der Endplatten zu einem kompakten mechanischen Modul zusammengefasst wird. Dadurch verringern sich Bauvolumen und Platzbedarf der Vorrichtung.The Invention provides that the fuel cell stack and the power electronics over at least one of the end plates to a compact mechanical module is summarized. This reduces the construction volume and space requirements of the Contraption.
Der Brennstoffzellenstapel und die Leistungselektronik werden über wenigstens eine der Endplatten zu einer stabilen Einheit verbunden, wodurch eine tragende Struktur entsteht. Da die verlängerten Endplatten des Brennstoffzellenstapels eine Tragstruktur für den Brennstoffzellenstapel und die Leistungselektronik sind, ist keine aufwändige Haltevorrichtung zur Befestigung der Leistungselektronik am Fahrzeug notwendig.Of the Fuel cell stack and the power electronics are over at least one of the end plates is connected to a stable unit, creating a load-bearing structure. Because the extended End plates of the fuel cell stack a support structure for the fuel cell stack and the power electronics are, is no elaborate holding device for attaching the power electronics on Vehicle necessary.
Weitere vorteilhafte Ausführungen und Ausgestaltungen der Erfindung ergeben sich aus den restlichen Unteransprüchen und werden anhand der Figuren in den nachfolgenden Ausführungsbeispielen exemplarisch erläutert.Further advantageous embodiments and embodiments of the invention arise from the remaining subclaims and will with reference to the figures in the following embodiments explained by way of example.
