METAL SEPERATOR FOR FUEL CELL INCLUDING AND FUEL CELL STACK HAVING THE SAME

摘要

PURPOSE: A metal separation plate for fuel cell is provided to improve the flow of the cooling water and to secure the flow path of reaction gas by utilizing the whole area of flow path in the metal separation plate. CONSTITUTION: A metal separtion plate(100) comprises a reaction gas channel(122) which is protrude from the first facet to the second facet; a channel part(120) with a cooling water channel(124) formed in between the channels of the reaction gas; a manifold(140) which is formed on both sides of the channel part; a cooling flow path terminal part which is formed between the manifold and the channel part; and a gasket which surraounds the channel part and the manifold. The cooling channel comprises a coolant main channels(124b) which are formed between the outer part of the reaction gas channel and the inner part of gasket; and a coolant sub-channels(124a) formed in between the channels of the reaction gas. The width of the coolant main channel is wider than the coolant sub channels.
