AIR SUPPLY APPARATUS FOR FUEL CELL AND FUEL CELL SYSTEM HAVING THE SAME

摘要

PURPOSE: An air supply apparatus is provided to reduce cooling performance of a stack by remarkably reducing cooling load of a radiator without increasing cooling capacity of a radiator. CONSTITUTION: An air supply apparatus(12) for a fuel cell supplying air to a stack(11) of the fuel cell comprises a compressor(18) generating charge air by compressing external air, a first cooling unit(20) arranged in a lower side of the compressor, consisting of a vortex tube, and separating charge air to low temperature charge air and high temperature charge air through an energy separation reaction, and a second cooling unit(40) arranged in a loser side of the first cooling unit, and cooling the low temperature charge air supplied from the first cooling unit by cooling water.
