Description

technical field

[0001] The invention relates to a structural design of a proton exchange membrane fuel cell, in particular to a sealing structure of a modular proton exchange membrane fuel cell. Background technique

[0002] In the technical field of fuel cells, the types of fuel cells currently developed are roughly divided into alkaline fuel cells, phosphoric acid fuel cells, solid oxide fuel cells, molten carbonate fuel cells, and proton exchange membrane fuel cells. type. Various fuel cells have their own advantages and disadvantages and application ranges, among which the proton exchange membrane fuel cell (PEMFC) has the most commercial value.

[0003] The working principle of the fuel cell is mainly to use hydrogen and oxygen to generate water through an electrochemical reaction and release electric energy, which can basically be regarded as an inverse device for water electrolysis.

[0004] Since the performance of the fuel cell efficiency depends on the completene...
