Problems solved by technology

But in this case, there is a disadvantage that as the volume of the separation plate becomes larger, the volume of the stack also becomes larger
[0012] In addition, in the case of the separation plate formed by molding a thin metal plate, it is difficult to separately manufacture a cooling channel similar to graphite

Abstract

Disclosed is an air-cooled metal separator which does not require cooling water. The air-cooled metal separator according to the present invention comprises: a channel part which includes reactive gas channels protruded from a front side to a back side at the center of a metal plate, and air flow passages formed between the reactive gas channels protruded to the back side; a first gasket which is continuously formed at the edge of the front side of the channel part; and a second gasket which is non-continuously formed at the edge of the back side of the channel part, wherein the non-continuous part serves as an air movement passage.

Description

technical field [0001] The present invention relates to a metal separator (Metal Separator) for a fuel cell, and more particularly relates to a non-continuous spacer that can be used to support a moving passage of air and a separator without supplying cooling water by means of air cooling (gasket) air-cooled metal separator plate. Background technique [0002] A fuel cell refers to a battery that directly converts chemical energy generated by fuel oxidation into electrical energy. Recently, in order to overcome the depletion of fossil fuels, the greenhouse effect caused by carbon dioxide, etc., and global warming, many researches such as solar cells are being carried out. [0003] Generally, a fuel cell converts chemical energy into electrical energy by utilizing the oxidation and reduction reactions of hydrogen and oxygen. At the negative electrode, hydrogen gas is oxidized and separated into hydrogen ions and electrons, and the hydrogen ions move to the positive electrod...
