Problems solved by technology

In this way, oxygen cannot be uniformly supplied to each position of the cathode surface of the fuel cell module 110, resulting in different reaction efficiencies of each fuel cell module 110, so the reliability of the fuel cell device 100, 100' is poor.
In addition, more blowing fans 130 are used to provide the airflow 50 in the known technology, which will consume more electric energy, resulting in poor output power of the fuel cell device 100, 100'
In addition, too many blowing fans 130 will generate excessive noise, and will cause the volume of the fuel cell device 100, 100' to be too large

Abstract

The invention discloses a fuel cell device which comprises a reacting unit, at least a fan and an air flow guiding device. The reacting unit is used for implementing chemical reactions, and the fan is used for provide air flows. The air flow guiding device is connected with the fan and the reacting unit, and is composed of a flow gathering section and a first flow dividing section. The flow gathering section is connected with the fan, and only one flow channel is formed in the flow gathering section. The first flow dividing section is connected with the flow gathering section, and is positioned between the flow gathering section and the reacting unit. The number of the flow channels in the first flow dividing section is N1, wherein N1 is a positive integer and is larger than.

Description

technical field [0001] The present invention relates to a battery, and more particularly to a fuel cell device. 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 the direct methanol fuel cell as an example, the fuel cell module of the direct methanol fuel cell includes a proton exchange membrane (proton exchange membrane) and a cathode (cathode) and an anode (anode) respectively 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 ...
