Abstract
Description
Die vorliegende Erfindung betrifft eine Methode zu einer Dichtebestimmung, insbesondere eine Rechenmethode für die Brennstoffdichte in einer Methanol-Brennstoffzelle.The The present invention relates to a method for density determination, in particular a calculation method for the fuel density in a methanol fuel cell.
In konventioneller Technik wird die Brennstoffdichte in Methanol-Brennstoffzellen allein durch Dichtesensoren bestimmt. Damit läßt sich die Aufgabe der Ermittlung von Brennstoffdichten lösen, jedoch in leichten, dünnen und kurzen Brennstoffzellen ist das Volumen von Dichtedetektoren entsprechend anzupassen. In kompakten Brennstoffzellen ist ein Einbau von Dichtesensoren nicht möglich.In Conventional technology is the fuel density in methanol fuel cells determined solely by density sensors. This can be the task of the investigation release from fuel densities, however, in light, thin and short fuel cells is the volume of density detectors adjust accordingly. In compact fuel cells is an installation of density sensors not possible.
Dieser Mangel läßt sich durch Anwenden einer Rechenmethode beheben, die eine Messung von Dichtewerten simuliert.This Lack can be by applying a calculation method that measures a density value simulated.
Die wesentliche Aufgabe der vorliegenden Erfindung besteht darin, eine Rechenmethode zur Bestimmung der Brennstoffdichte während elektrochemischer Reaktionen in einer Methanol-Brennstoffzelle ohne Messung zu schaffen.The essential object of the present invention is a Calculation method for determining the fuel density during electrochemical To provide reactions in a methanol fuel cell without measurement.
Eine weitere Aufgabe der vorliegenden Erfindung besteht darin, einen Dichtesensor zu ersetzen, um die Brennstoffdichte während elektrochemischer Reaktionen in einer Methanol-Brennstoffzelle ohne Messung zu bestimmen.A Another object of the present invention is to provide a Density sensor to replace the fuel density during electrochemical reactions in a methanol fuel cell without measurement to determine.
Um diese Aufgaben zu erfüllem, weist die vorliegende Erfindung mehrere Schritte auf: Eine Brennstoffzelle wird bereitgestellt. Wenigstens ein Musters von Brennstoff bekannter Dichte zur Versorgung von Brennstoffzellen wird bereitgestellt, um unter verschiedenen Dichten in elektrochemischen Reaktionen Strom zu erzeugen. Unter verschiedenen Dichten werden Messungen und Aufzeichnungen mehrerer physikalische Parameter durchgeführt. Von den physikalischen Parametern werden drei ausgewählt und dienen als Basis einer dreidimensionalen Darstellung, die Interpolationsbestimmungen von Brennstoffen unbekannter Dichte erlaubt. In diesen wird Brennstoff unbekannter Dichte zugeführt und erzeugt Strom. Die ausgewählten drei physikalischen Parameter werden gemessen, und eine Interpolationsrechnung wird durchgeführt, die die gesuchte Brennstoffdichte ermittelt.Around to fulfill these tasks, For example, the present invention has several steps: a fuel cell will be provided. At least one pattern of fuel more familiar Density to supply fuel cells is provided to stream under different densities in electrochemical reactions to create. Under different densities are measurements and records of several physical parameters performed. Of the physical parameters, three are selected and serve as the basis of a three-dimensional representation, the interpolation determinations allowed by fuels of unknown density. In these will be fuel fed to unknown density and generates electricity. The selected ones three physical parameters are measured, and one interpolation calculation is carried out, which determines the sought fuel density.
