Device and method for horizontally loading fuel cell stacks

Abstract

The invention discloses a device for horizontally loading fuel cell stacks. The device comprises a driving device, a stack pressing device and a horizontal base, wherein the stack pressing device consists of a first pressing plate and a second pressing plate and is arranged on the horizontal base, the opposite surfaces of the first pressing plate and the second pressing plate are parallel mutually and are perpendicular to the horizontal base, and templates for fixing end plates on two ends of a fuel cell are respectively arranged on the opposite surfaces of the first pressing plate and the second pressing plate; a plurality of positioning holes are correspondingly formed in the two templates and used for mounting external positioning rods of the fuel cell stacks; the second pressing plate is driven under the control of a control system to horizontally move to the first pressing plate, and a stack assembly inserted between the two templates can be pressed tightly. The first pressing plate and the second pressing plate are perpendicularly arranged on the horizontal base, so that the fuel cell stacks can be horizontally loaded, and two ends of the stack assembly are stressed evenly so as not to cause performance difference from two ends of the stack.

Description

technical field [0001] The present invention relates to the field of fuel cells, in particular to the field of electric stack assembly of fuel cells. Background technique [0002] Fuel cell (PEMFC) technology is the most efficient means of utilizing hydrogen energy. A fuel cell is a device that directly converts the chemical energy of hydrogen into electrical energy. It has the advantages of high efficiency, low noise, and zero pollution, and is playing an increasingly important role in today's society. Fuel cells usually need to assemble multiple single cells in series to form a stack. The main components include bipolar plates, membrane electrodes, end plates, fasteners, etc. The accuracy and uniformity of the force during the assembly process of the stack determines the performance of a stack. [0003] The automation degree of traditional stack assembly machines is not high, and most of them are vertical hydraulic presses. For example, the patent with the publication nu...

AI Technical Summary

Problems solved by technology

The device determines the height of the stack assembly through the scale on the guide rod and the vertical rod. It relies on manual operation to assemble the stack, which wastes time. At the same time, the uniformity of the stack is poor, the force on the stack components is uneven, and the performance is low, which is not conducive to the fuel cell industry. development
