The converter assembly 10 may be, but is not limited to being, a Direct Current-Direct Current (DC-DC) converter assembly 10. The converter assembly 10 may be, but is not limited to being, applied to the fuel cell system 1, and it is to be understood that in other embodiments of the present application, the converter assembly 10 may also be applied to other scenarios, and the scenario in which the converter assembly 10 is applied should not be construed as limiting the converter assembly 10 provided in the present embodiment.

Preferably, in the schematic diagrams of the embodiments of the present application, the first conductive member 12 is illustrated as a copper bar, so that the occupied space of the first conductive member 12 in the converter assembly 10 can be reduced compared with the connection of a wire harness, which is beneficial to improving the space utilization efficiency of the converter assembly 10, and the production cost of the converter assembly 10 can be effectively reduced compared with the connection modes such as a connector.

Preferably, the first conductive element 12 may be a flexible conductive element, that is, the first conductive element 12 is flexibly deformable, so that the first conductive element 12 is not easily damaged due to collision. For example, in one embodiment of the present application (fig. 11, 12, 13), the first conductive member 12 may be electrically connected to the stack assembly 20 in the fuel cell system 1 when the converter assembly 10 is applied to the fuel cell system 1. Specifically, the first conductive member 12 may be electrically connected to the second conductive member 22 of the galvanic pile assembly 20, and in the installation process of the first conductive member 12 and the second conductive member 22, since the converter assembly 10 and the galvanic pile assembly 20 are two relatively large components with relatively large installation dimensional tolerance, the first conductive member 12 and the second conductive member 22 are easy to collide, and therefore, when the first conductive member 12 is configured as a flexible conductive member, damage caused by collision between the first conductive member 12 and the second conductive member 22 can be effectively avoided.

Further, the first conductive element 12 may be, but is not limited to being, partially flexibly deformable, or fully flexibly deformable.

The first conductive element 12 further includes a conductive body 121 and a first through hole 122.

Further, the material of the positioning member 13 may be, but is not limited to, metal, plastic, or other composite materials. The number of the positioning members 13 may be, but is not limited to, one, two, three, or other numbers.

Further, the shape of the second through hole 132 may be, but not limited to, circular, square, oval, or other irregular shapes. The number of the second through holes 132 may be, but is not limited to, one, two, three, four, or other numbers.
