Abstract: PURPOSE: Cooling system of fuel cell is provided to prevent local efficiency reduction by reducing the generation of temperature difference in a coolant inflow part and a coolant outflow part, thereby improving the power of whole fuel cell stack, and the durability of a stack. CONSTITUTION: Cooling system of fuel cell for vehicle comprises a circulation loop of coolant for cooling a fuel cell stack in which a plurality of fuel cell is stacked. The circulation loop comprises: a coolant inflow ports(140a,140b) in which coolant passing stack is flowed in; a coolant outflow ports(140c,140d) for outflowing coolant passed the stack, formed to be corresponding with the coolant inflow ports; and a plurality of coolant channels(150,160) connecting the plurality of coolant inflow ports and corresponding outflow ports. The plurality of coolant channels is formed to flow coolant toward directions different each other.

Abstract: PURPOSE: Ion-exchange filter is provided to prevent the outflow of coolant through a mounting part at attaching/detaching an ion-exchange filter, and to increase degree of location freedom about package layout of the ion-exchange filter. CONSTITUTION: An ion-exchange filter mounting unit filter comprises a housing(11), an ion exchange filter(15) removing ionically electroconductive material in coolant. A mounting unit(100) for attaching/detaching the ion-exchange filter to a specific mounting part(20) in a coolant flow pathway of fuel cell system comprises a connection part(30) projected to the upper part of the housing in order to connecting to the inside of the housing, and capable of male-female coupling, and a switch part(70) selectively opening and closing the coolant flow pathway by being elastically deformed by the connection part.
