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

In a cathode plate (1, 1') of a bipolar element, the cathode plate has: a first plate side (2) on which a cathode channel structure (3) for distributing an oxidizing agent is constructed; and the first plate The second plate side (15) facing away from the side (2), on which the cooling channel structure (16) for distributing the coolant is formed, the invention provides a solution by means of a structurally simple The method provides an improved and installation-space-saving fuel cell stack. This problem is solved by constructing at least one channel (14) extending from the first plate side (2) to the second plate side (15) through the entire cathode plate (1, 1'), the channel connecting the cathode channel The structure (3) and the cooling channel structure (16) are fluidly connected.

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)...
