Fuel battery vehicle anode hydrogen/oxygen interface formation suppressing structure

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 [0001] 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 [0002] 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. [0003] Since the high polymer electrolyte fuel cell in the above cell has...

Problems solved by technology

[0007] Therefore, there is a problem that the carbon support material on the cathode side is corroded and disappears later, spoiling the overall performance of the stack
