Problems solved by technology

The manufacturing process of metal partitions is complicated because it is difficult to install one metal partition on another
In addition, the added metal plate increases the weight of the battery pack, thereby putting a lot of load on the device where the fuel cell system is installed

Embodiment Construction

[0060] A metal separator for a fuel cell and a fuel cell stack having the separator according to preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0061] figure 1 and 2 is a view showing a partition according to a preferred embodiment of the present invention. The metal separator 100 includes a reaction gas manifold 130 , a coolant manifold 120 , a reaction gas passage 140 , a coolant passage 150 , a coolant passage connection part 110 and a coolant passage connection path 112 . In addition, the gasket 200 is adhered to the metal separator 100 to prevent reaction gas and coolant from leaking from the metal separator 100 . The reaction gas manifold 130 is used to supply reaction gas to the metal separator 100 . Typically, the reactant gas manifold 130 is located on one side of the metal separator 100. The reaction gas introduced to the metal separator 100 through the reaction gas manifold 130 is gu...

Abstract

The present invention discloses a metal separator for a fuel cell including a reaction gas channel formed to protrude from a first face of the metal separator to a second face thereof, a coolant channel formed between the reaction gas channels protruding from the second face of the metal separator, a reaction gas manifold opened to introduce a reaction gas into the metal separator, a coolant manifold opened to introduce a coolant into the metal separator, and a stepped portion positioned at any one of the space between the reaction gas channel and the reaction gas manifold, and the reaction gas channel. This configuration serves to widen the reaction gas flowing portion and the coolant flowing portion on the metal separator, and prevent deformation of the reaction gas flowing portion and the coolant flowing portion, thereby improving efficiency of the fuel cell.

Description

technical field [0001] The present invention relates to a metal separator for a fuel cell and a fuel cell stack having the same, and more particularly, the present invention relates to a metal separator for a fuel cell including a reactant gas passage and cooling A coolant channel, and it further includes a coolant inlet and an outlet connecting the coolant channel, and relates to a fuel cell stack having the separator. [0002] In addition, the present invention relates to a metal separator for a fuel cell, which includes a structure for preventing deformation of a reactant gas inflow portion, and to a fuel cell stack having the same. Background technique [0003] In general, a fuel cell is a power generation device that converts chemical energy into electrical energy by using oxidation and reduction of hydrogen and oxygen. Hydrogen is oxidized at the anode to be separated into hydrogen ions and electrons. Hydrogen ions are transported to the cathode through the electrol...
