Description

Sliding table for fuel cell stack tester

Technical Field

The utility model relates to a fuel cell technical field, concretely relates to a slip table for fuel cell pile test machine.

Background

Before each proton exchange membrane fuel cell stack is used, the stack is activated to enable the performance of the stack to reach a usable standard, and then the stack can enter a use and installation procedure to be used formally. The electric pile is not activated, the performance of the electric pile can not be fully exerted, and the whole electric pile can not be used due to low single-section performance. The activation of the galvanic pile before use can not only fully exert the performance of the galvanic pile, but also can be used for checking the galvanic pile product. Therefore, activation of the stack before use and installation are essential steps for the industrialization of fuel cell stacks. In the prior art, the galvanic pile is directly arranged on the workbench, and the pipeline is adopted to connect the activation device, so that the movement and connection are complicated and inconvenient.

Disclosure of Invention

The utility model provides a slip table for fuel cell pile test machine.

The technical scheme of the utility model:

a sliding table for a fuel cell stack testing machine is characterized in that a plurality of bases are uniformly distributed on a table board of the testing machine, the bases are fixedly connected with the table board of the testing machine, arc grooves are formed in the tops of the bases, balls are arranged in the arc grooves and are in sliding contact with the bases, the tops of the balls extend out of the arc grooves, and the tops of all the balls are coplanar to form the sliding table;

the electric pile is arranged on the sliding table and is connected with an activating device of the testing machine through a joint; the stack is supported on all the balls.

By adopting the device, the galvanic pile is supported on the ball, so that an operator can easily push the galvanic pile to roll on the ball and move in any horizontal direction; the convenient operating personnel fixes a position and connects galvanic pile and activation device and carry out the galvanic pile activation, as to the concrete structure of activation device and how to activate the galvanic pile, has already publicly documented in the prior art, like the patent: CN201510428734.4 is related to a fuel cell stack activation device, and is not described herein.

All the joints are respectively connected with the activating device through pipelines; part of the joints are fixed joints which are fixedly arranged on the rack, and part of the joints are movable joints which are fixedly arranged on a fixed plate; the air cylinder drives the fixed plate to be close to the galvanic pile, the interfaces in front of the galvanic pile are inserted into the movable joints in a one-to-one correspondence mode and are connected with the movable joints, the movable galvanic pile is pushed to be close to the fixed joints, and the interfaces in back of the galvanic pile are inserted into the fixed joints in a one-to-one correspondence mode and are connected with the fixed joints.

A coaming is arranged on the table top of the testing machine in a circle, and the height of the coaming is lower than that of the top of the ball.

The utility model has the advantages that the design is reasonable, the structure is simple, the galvanic pile is arranged on the ball, the movement of the galvanic pile in any horizontal direction can be easily realized, the galvanic pile is convenient to be disassembled and assembled for activation, and the time and the labor are saved; the effect is particularly remarkable when the activation is carried out on a large-batch galvanic pile.
