Embodiment Construction

[0014] In the single attached figure, the fuel cell system 1 can be seen in a very strongly schematic view. In this case, the fuel cell system 1 is designed for installation in the indicated vehicle 2 . The core of the fuel cell system 1 is the fuel cell 3 , which should be designed as a PEM fuel cell by way of example. In its interior, the fuel cell 3 essentially has three spaces arranged separately from one another, which are each realized in the usual construction in individual cells which are then stacked to form a fuel cell group, the so-called stack. The individual spaces of the cells of the fuel cell stack 3 are then connected to one another via corresponding line elements or current collectors. Here, the spaces shown in the figure are positive electrode chamber 4 , negative electrode chamber 5 , and space 6 through which a liquid cooling medium flows in the example of a battery cell, and this space may also be called a heat exchanger for cooling. The negative electro...

Abstract

The invention relates to a method for cooling a fuel cell (3) having a liquid cooling medium, wherein, of the educts supplied to the fuel cell and the products discharged from the fuel cell, at least one is gaseous during operating conditions, wherein the cooling medium is delivered through the fuel cell (3) by a coolant delivery device (11). The invention is characterized in that the power consumption of the coolant delivery device (11) is compared with predetermined reference values in order to identify gas in the liquid cooling medium in the event of a discrepancy between the power consumption and the predetermined reference values.

Description

technical field [0001] The invention relates to a method for cooling a fuel cell with a liquid cooling medium according to the type defined in the preamble of claim 1 . Background technique [0002] Fuel cell systems are known from the general prior art. These fuel cell systems generate electrical power using a fuel cell, which may be designed, for example, as a PEM fuel cell. In addition to the electrical power and the product water, a certain amount of waste heat is always generated in the fuel cell, which waste heat is undesired and according to the prior art is dissipated from the region of the fuel cell by means of a liquid cooling medium. Typically, a liquid cooling medium is conveyed in the cooling circuit by at least one coolant conveying device and flows on the one hand through the fuel cell for absorbing waste heat and on the other hand through a heat exchanger which acts as a heat sink for dissipating the absorbed heat. The residual heat is, for example, dissipa...
