Embodiment Construction

[0023] Hereinafter, referring to the accompanying drawings, preferred embodiments of the present invention will be described. Through these examples, those skilled in the art can fully understand the present invention, but the present invention can be modified in various forms, and the scope of the present invention is not limited to these specific examples.

[0024] attached figure 1 The anode side of the hydrogen / oxygen interface formation suppression structure for the fuel cell vehicle of the present invention. Figure 2-Figure 5 A specific example of the anode side of the hydrogen / oxygen interface formation suppressing structure of the fuel cell vehicle of the present invention is shown.

[0025] refer to Figure 1-Figure 5 , the present invention includes a first hydrogen exhaust pipe 100 extending to the outside of the stack 2, and includes a three-way valve 110 for allowing the hydrogen supplied to the anode 4 of the stack 2 to be released, thereby changing the flow r...

Abstract

The present invention relates to an anode side hydrogen / oxygen interface formation inhibition structure of a fuel cell vehicle which prevents a high voltage field due to hydrogen / oxygen interface formation from being formed so that a stable stack driving may be realized when the fuel cell vehicle starts up or shuts down.

Description

[0001] Related application reference [0002] This application claims and benefits from the benefit of priority of Korean Patent Application No. 10-2006-0105258 filed with the Korean Intellectual Property Office on October 27, 2006, which is incorporated herein by reference. technical field [0003] The present invention relates to a hydrogen / oxygen interface formation suppression structure on the anode side of a fuel cell vehicle to prevent the formation of a high pressure region due to the hydrogen / oxygen interface, so that a stable stack drive (stable stack) can be achieved when the fuel cell vehicle is started or shut down driving). Background technique [0004] In general, a fuel cell is mainly composed of an electrode for an electrochemical reaction, an electrolyte film for transferring hydrogen ions generated by the reaction, and a bipolar plate for maintaining the electrodes and electrolyte. [0005] Since the high polymer electrolyte fuel cell in the above cell has...
