The utility model provides a lift force/resistance force type vertical axis wind driven generator blade which comprises a vertically-arranged wing type blade, wherein an airflow passageway with an arc transverse cross section is arranged on the blade, openings of the airflow passageway are arranged on two side faces of the blade, the cambered surface of the airflow passageway faces to the front edge of the blade, and the concave cambered surface of the airflow passageway faces to the back edge of the blade. After the lift force/resistance force type vertical axis wind driven generator blade provided by the utility model is used, airflow generates a pressure difference on the wing-shaped surface of the blade to provide lift force acting, airflow generates a resistance force in the arc airflow passageway of the blade to provide resistance force type acting, and the blade has the characteristics of lift force type blade and resistance force type blade at the same time, so that the blade is larger in torque, higher in tip speed ratio, and good in starting performance. Meanwhile, according to the overlap between the lift force type acting and the resistance force type acting, the wind energy conversion rate of the blade can be greatly improved.
