Problems solved by technology

When using such fuel cell stacks both statically and mobilely, solutions for removing liquid water must be integrated, which leads to expensive installations with a larger installation volume, especially in the case of external applications with ambient conditions below 0° C. solution, thereby increasing production costs

Embodiment Construction

[0034] Figure 1 to Figure 6 Different views of the cathode plate 1 according to the invention according to the first embodiment are shown, correspondingly in Figure 7 and Figure 8 A second embodiment of a cathode plate 1' according to the invention is shown in .

[0035] As is known from the prior art and explained above, the cathode plate 1 , 1 ′ corresponds to a partial plate which, together with the anode plate, not shown in detail in the figures, forms a fuel cell for air cooling stack of bipolar components. In this case, such a fuel cell stack has a plurality of such bipolar elements, between which corresponding membrane electrode assemblies (MEAs) are arranged and which delimit individual fuel cells.

[0036] reference in Figure 1 to Figure 6 The first embodiment of the cathode plate 1 shown in figure 1 The top view of shows the first plate side 2 of the cathode plate 1 . A cathode channel structure 3 is formed on the first plate side 2 of the cathode plate 1 ,...

Abstract

The invention relates to a cathode plate (1, 1') of a bipolar element, comprising a first plate side (2), on which a cathode channel structure (3) for distributing an oxidant is formed, and a second plate side (15), which faces away from the first plate side (2) and on which a cooling channel structure (16) for distributing a coolant is formed. The problem addressed by the invention is that of creating a solution by means of which an improved and installation-space-saving fuel cell stack is provided by using simple design. This problem is solved in that at least one passage (14) extending fromthe first plate side (2) to the second plate side (15) is formed through the cathode plate (1, 1'), which passage fludically connects the cathode channel structure (3) and the cooling channel structure (16).

Description

technical field [0001] The invention relates to a cathode plate of a bipolar element, which has: a first plate side, on which a cathode channel structure for distributing an oxidant is constructed; a second plate side opposite to the first plate side, on which The top is constructed with a cooling channel structure for distributing the coolant. The invention also relates to a method for operating a cathode plate of a fuel cell, wherein the cathode plate has: a first plate side on which a cathode channel structure for distributing the oxidizing agent is formed; a second plate side facing away from the first plate side On the side of the second plate, a cooling channel structure for distributing the coolant is constructed on it, and wherein the coolant and the oxidant are respectively delivered to the cathode plate. Background technique [0002] The basic structure of a fuel cell and in particular a polymer-electrolysis-membrane-fuel cell (abbreviation PEMFC or PEM-fuel cell)...
