Embodiment Construction

[0041] first involves Figure 1 to Figure 5 . especially in Figure 1 to Figure 4 The media supply plate 10 shown in has an upper plate 44 and a lower plate 46 . The lower plate 46 is designed to cooperate with the upper plate 44 to provide gas pipelines 22, 24, 26, 28, wherein the gas pipeline 22 is connected to the anode gas interface 14, the gas pipeline 24 is connected to the cathode gas interface 16, and the gas pipeline 26 is connected to the cathode gas interface 16. The anode exhaust gas interface 18 is connected and the gas pipeline 28 is connected with the cathode exhaust gas interface 20 . The anode gas connection 14 , the cathode gas connection 16 , the anode waste gas connection 18 and the cathode waste gas connection 20 are respectively designed to be tubular and fixed on the flange connecting plate 74 vertically arranged with the upper plate 44 and the lower plate 46 . The upper plate 44 , the lower plate 46 and the flange connection plate 74 are connected to...

Abstract

The invention relates to a media supply plate (10) for a fuel cell stack (12), comprising at least on anode gas connection (14) and at least one cathode gas connection (16). According to the invention, the media supply plate (10) also comprises at least one anode waste gas connection (18) and at least one cathode waste gas connection (20). The invention also relates to a fuel cell system (52) using said type of media supply plate (10) and to a method for producing said type of fuel cell system.

Description

technical field [0001] The invention relates to a medium supply plate of a fuel cell stack with at least one anode gas connection and at least one cathode gas connection. [0002] The invention also relates to a fuel cell system and a method of manufacturing such a fuel cell system. Background technique [0003] Especially for high-temperature fuel cell systems, such as SOFC fuel cell systems, it is currently customary to subsequently integrate the separately produced fuel cell stack into a system for operating the fuel cell stack. Such an integration of the fuel cell stack into the respective system is very complex since, for example, the gas required for the operation of the fuel cell stack must be supplied or exported. In addition, integration of fuel cell stacks into systems often requires seals between the system and the fuel cell stack, where such seals can become a safety hazard if the seal is not tight, such as by causing leaks such as The recombinant flows into an...
