The present invention relates to a turbo blower for a fuel cell having an integrated cooling structure. Specifically, in a turbo blower 1 for a fuel cell having a complex cooling structure, A blower casing means (100) for guiding the flow and discharge of the sucked air; And an impeller means (200) located inside the blower casing portion (100) for generating inflow and flow of air, In the blower casing means 100, An impeller means cooling air cooling unit 150 for cooling the impeller means 200 by using the flow of air sucked into the blower casing means 100 by the impeller means 200, And an impeller means cooling unit 160 for cooling the impeller means 200 by using the flow of cooling water supplied from the outside, The temperature rise of the impeller means 200 rotated at high speed is reduced, and efficiency and durability are maximized. Accordingly, the present invention has an advantage of providing a turbo blower for a fuel cell in which the temperature rise of the impeller means 200 is prevented to improve efficiency and durability. |
