The present invention relates to a turbo-blower having a complex cooling structure for a fuel cell, and more specifically, to a turbo-blower having a complex cooling structure for a fuel cell, the turbo-blower providing improved efficiency and durability of an impeller means by inhibiting a temperature rise through cooling of the impeller means that generates high-pressure air, by a cooling structure configured to simultaneously utilize both an air-cooling method and a water-cooling method. 11200{'b': '100', 'a blower casing means () that guides flow and discharge of suctioned air; and'}{'b': 200', '100', '100, 'an impeller means () that is positioned inside the blower casing means () and is coupled to the blower casing means () and generates inflow and flow of air,'}{'b': 100', '200, 'claim-text': [{'b': '110', 'an air suction duct () that allows air to be suctioned inside;'}, {'b': 120', '200', '200, 'an air flow guiding cover () that is formed to have a curved surface, is air-tightly coupled to the impeller means () at a neighboring position, and guides air suctioned inside to the impeller means ();'}, {'b': 130', '200, 'an air emitting duct () that causes air subjected to a pressure rise through the impeller means () to be discharged to a fuel cell stack;'}, {'b': 140', '100, 'a suctioned air securing portion () that causes an amount of air suctioned inside the blower casing means () to be secured;'}, {'b': 150', '200', '100', '200, 'an impeller means air-cooling portion () that cools the impeller means () by using flow of air suctioned inside the blower casing means () by the impeller means ();'}, {'b': 160', '200', '200', '161, 'an impeller means water-cooling unit () that is formed to neighbor the impeller means (), cools the impeller means () by using flow of cooling water supplied from outside, and has a cooling-water inflowing/circulating groove ();'}, {'b': 170', '110', '150', '120, 'a first air flow path () that is generated by the air suction duct (), ...
