The invention belongs to a fuel cell hydrogen circulating pump structure in the technical field of fuel cell parts. The pump head cover plate (1), the pump head shell (2) and the motor shell (3) are connected through bolts (6); the controller cover plate (4) and the motor shell (3) are connected through bolts (7), a motor rotor (10) and a pump head impeller (11) of the motor are fixedly installed on a transmission shaft (9), a motor inner cavity (I) and a controller inner cavity (II) are formed in the motor shell (3) and are of a mutually isolated structure through a partition plate (18), the motor is installed in the motor inner cavity (I), and the pump head impeller (11) is installed in the controller inner cavity (II). A controller is installed in the controller inner cavity (II), and the partition plate (18) is perpendicular to the axis of the motor shell (3). According to the hydrogen circulating pump structure of the fuel cell, the number of parts is reduced, the cost is reduced, and failure modes are r
