Problems solved by technology

However, in general practical applications, when the pressure is increased enough to remove the water droplets in the gas channel, the proton exchange membrane will be displaced, peeled off, cracked or damaged because it cannot withstand the pushing force caused by the pressure. Phenomenon

Abstract

A pressure regulating structure of air inlet on reaction polar plate at fuel cell is prepared as arranging at least one air inlet and at least one air outlet as well as multiple air channel at central region of said reaction polar plate, covering a proton exchange film set on said central region simultaneously, arranging various said air channels to be parallel with each other, setting a narrow opening end and a wide opening end on each said air channel as well as setting sectional area of narrow opening end to be less than that of wide opening end.

Description

technical field [0001] The invention relates to a fuel cell group, in particular to a gas inlet pressure regulating structure of a fuel cell reaction plate. Background technique [0002] With the progress of human civilization, the consumption of traditional energy such as coal, oil and natural gas continues to increase, causing serious pollution of the earth, leading to the deterioration of the environment such as greenhouse effect and acid rain. Human beings have clearly realized that the stock of natural energy is limited, and if it continues to be abused, it will be exhausted in the near future. Therefore, the world's advanced countries have recently been devoting themselves to the research and development of new alternative energy sources, and fuel cell packs are one of the most important options with development potential and practical value. Compared with the traditional internal combustion engine, the fuel cell stack has many advantages such as high energy conversio...
