Description
Die Erfindung bezieht sich auf eine Verdichtersteuerung gemäß dem Oberbegriff des unabhängigen Anspruchs.The The invention relates to a compressor control according to the preamble of the independent Claim.
Zum Betrieb einer Brennstoffzelle ist ein bestimmter Druck auf der Gas- und der Luftseite erforderlich, der den Wirkungsgrad entscheidend beeinflusst. Mit zunehmender Verdichterarbeit wird jedoch der Systemwirkungsgrad einer Brennstoffzellenanlage, die einen Reformer, einen Verdichter, Pumpen, die eigentliche Brennstoffzelle und weitere Komponenten umfasst, reduziert. Daher ist es notwendig, einen geringen Druckverlust im System zu erreichen.To the Operation of a fuel cell is a certain pressure on the gas and the air side required, which determines the efficiency affected. However, with increasing compressor work, the system efficiency becomes a fuel cell plant comprising a reformer, a compressor, Pumps, the actual fuel cell and other components includes, reduced. Therefore, it is necessary to have a low pressure loss in the system.
Für eine gasseitige Sicherheitskette sind bei Gasgeräten zwei voneinander unabhängige Gasventile erforderlich, von denen eines in der Regel auch eine Gasdurchsatzregelung vornimmt. Bei einer Brennstoffzellenanordnung mit einem Verdichter muss jedoch sichergestellt werden, dass bei einem Betrieb des Verdichters die Gasventile geöffnet sind. Andernfalls könnte durch den Verdichter ein Unterdruck in den Gasleitungen gegenüber dem Atmosphärendruck erzeugt werden, der das Eindringen von Luft in den Gasweg möglich macht.For a gas side Safety chain are on gas appliances two independent Gas valves required, one of which is usually a Gas flow rate control makes. In a fuel cell assembly with a compressor, however, must be ensured at an operation of the compressor, the gas valves are open. Otherwise, could through the compressor is a negative pressure in the gas lines relative to the atmospheric pressure be generated, which makes the penetration of air into the gas path possible.

Ziel der Erfindung ist es, eine Verdichtersteuerung der eingangs erwähnten Art vorzuschlagen, die sich durch einen einfachen Aufbau auszeichnet.aim The invention is a compressor control of the type mentioned to propose, which is characterized by a simple structure.
Erfindungsgemäß wird dies bei einer Verdichtersteuerung der eingangs erwähnten Art durch die kennzeichnenden Merkmale des unabhängigen Anspruchs erreicht.According to the invention this is in a compressor control of the type mentioned by the characterizing Features of the independent claim reached.
Durch die vorgeschlagenen Maßnahmen ergibt sich ein sehr einfacher Aufbau, bei dem sich im Normalbetrieb ein nur sehr geringer Druckverlust ergibt.By the proposed measures This results in a very simple structure in which in normal operation a very low pressure loss results.
Durch die vorgeschlagenen Maßnahmen wird es möglich, dass bei geöffnetem elektromagnetisch betätigtem Gasventil der Verdichter anläuft, wobei er zunächst einen Unterdruck an der Saugseite aufbaut, wodurch sich das Rückschlagventil öffnet. Das Rückschlagventil ist so ausgelegt, dass es beim Anliegen des normalen Gasanschlußdruckes geschlossen bleibt, auch wenn das zweite Ventil geöffnet ist. Damit wird ein zu großer Unterdruck im Gasweg vermieden, und der Verdichter beginnt an seiner Druckseite einen Überdruck aufzubauen. Ist dabei ein bestimmter Druck oder Druckverlust erreicht, so öffnet das druckabhängig gesteuerte Gasventil und das Rückschlagventil schließt.By the proposed measures will be it is possible that when open Electromagnetically actuated Gas valve of the compressor starts, being first builds a negative pressure on the suction side, whereby the check valve opens. The check valve is designed to withstand the normal gas connection pressure remains closed, even if the second valve is open. This is too big Negative pressure in the gas path avoided, and the compressor starts at its pressure side an overpressure build. Is this a certain pressure or pressure loss reached, so opens the pressure-dependent controlled gas valve and the check valve closes.
Durch die Merkmale des abhängigen Anspruches ist es ebenfalls möglich, eine Regelung des Gasdurchsatzes vorzunehmen.By the characteristics of the dependent Claim it is also possible to regulate the gas flow rate.
