Problems solved by technology

This will cause greater resistance to gas flow, resulting in poor reaction efficiency of the fuel cell device 100
In addition, in order to improve the reaction efficiency of the fuel cell device 100, if a fan with a larger size and higher power is used instead, it will take up more space and consume more energy.
[0012] Similarly, if the anode flow channel plate 114 is made of plastic injection molding, it will also lead to poor reaction efficiency of the fuel cell device 100

Abstract

The invention discloses a flow channel plate which is used in a fuel cell device. The flow channel plate comprises a separation membrane and a plurality of strip-shaped support elements, wherein, the separation membrane is arranged between two components of the fuel cell device, and the strip-shaped support element is leaned against the separation membrane and the two components so as to maintainthe space between the two components. The flow channel plate has the advantage of lower flow resistance.

Description

technical field [0001] The present invention relates to a fuel cell apparatus, and in particular to a flow channel plate of the fuel cell apparatus. Background technique [0002] Fuel cells have the advantages of high efficiency, low noise, and no pollution, and are energy technologies in line with the trend of the times. Fuel cells are classified into various types, and the common ones are proton exchange membrane fuel cells (protonexchange membrane fuel cell, PEMFC) and direct methanol fuel cells (direct methanol fuel cell, DMFC). Taking a direct methanol fuel cell as an example, the fuel cell module of the direct methanol fuel cell includes a proton exchange membrane and cathodes and anodes disposed on both sides of the proton exchange membrane. [0003] The direct methanol fuel cell uses methanol aqueous solution as fuel, and the reaction formula of the direct methanol fuel cell is as follows: [0004] Anode: CH 3 OH+H 2 O→CO 2 +6H + +6e - [0005] Cathode: 3 / 2O ...
