Abstract

The invention relates to a series-parallel connection type universal stack positioning device for fuel cells. The positioning device realizes continuous adjustable size through the series-parallel connection of slide rails and positioning columns, so that it can adapt to fuel cell end plates and fuel cell end plates of different design sizes. Bipolar plates provide precise positioning for the assembly process of battery stacks of various design sizes. Through the above design, the positioning device provided by the patent of the present invention has the characteristics of simplifying the design of the positioning pin of the traditional bipolar plate, improving the assembly accuracy of the battery stack, adapting to various fuel cell design dimensions, being stable, and adjustable.

Description

technical field [0001] The invention relates to the technical field of a cell stack assembly and positioning device for a proton exchange membrane fuel cell, in particular to a slide rail serial / parallel connection type universal stack positioning device for a fuel cell. Background technique [0002] At present, green and environmentally friendly energy technology is an international research hotspot. After hydrogen energy is used, only water is produced, and hydrogen can be produced by electrolysis of water. It is considered to be the most ideal green and recyclable energy. Proton exchange membrane fuel cell is a power generation device that uses hydrogen as fuel. Its application fields include distributed power stations, electric vehicle drive power, emergency power, portable power, etc. It is an ideal hydrogen energy utilization device. [0003] The proton exchange membrane fuel cell is assembled from key components such as membrane electrodes, the core power generation c...
