Embodiment 1

[0023] refer to Figure 1-5 , the present embodiment relates to a fuel cell reaction device, in specific use; the cathode fuel enters the cathode chamber 2c from the cathode fuel inlet channel 7 (see Figure 5 ), the anode material enters the anode chamber 2b from the anode fuel inlet channel 9 (see image 3 ); After fully reacting, the cathode fuel flows out from the cathode fuel outlet channel 6 (see image 3 ), the anode material flows out from the anode fuel outlet channel 4 (see Figure 5 ); Simultaneously, the cooling fluid flows through the cooling plate 2a from the cooling fluid inlet passage 8, and flows out from the cooling fluid outlet passage 5 after cooling the cathode chamber 2c and the anode chamber 2b (see Figure 4 ).

[0024] The fuel cell reaction body 2 is "cooling plate 2a—anode chamber 2b—proton exchange membrane 2d—cathode chamber 2c—cooling plate 2a—anode chamber 2b—proton exchange membrane 2d—cathode chamber 2c..." Plate heat exchanger structure; h...

Abstract

The invention discloses a fuel cell reaction device. The fuel cell reaction device comprises a fuel cell reaction body and a box body, wherein the fuel cell reaction body is placed in the box body and is formed by sequentially splicing a cooling plate, a positive electrode chamber, a proton exchange membrane and a negative electrode chamber, a negative electrode fuel inlet passage, a cooling fluid inlet passage and a positive electrode fuel inlet passage are arranged at an upper end of the fuel cell reaction body at intervals, and a positive electrode fuel outlet passage, a cooling fluid outlet passage and a negative electrode fuel outlet passage are arranged at a lower end of the fuel cell reaction body at intervals. The fuel cell reaction device is used as the fuel cell reaction body and simultaneously used as a fuel cell heat sink, the reaction device and the heat sink are integrated, a negative electrode fuel and a positive electrode fuel perform chemical reaction through various passages, the fuel reaction area is expanded due to the narrow and zigzag passages, and the fuel reaction efficiency is improved; and the fuel cell reaction device is compact in structure and small in occupancy area, and the power of the fuel cell is improved.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, in particular to a fuel cell reaction device. Background technique [0002] After nearly 20 years of rapid development, proton exchange membrane fuel cell technology has made great progress and successfully solved many problems. However, in order to realize proton exchange membrane fuel cells, there are still problems such as low volume specific power, thermal safety problems caused by reaction heat, and high cost, which limit its commercialization in electric vehicles and other fields. In order to realize the commercialization of fuel cell electric vehicles, the performance of fuel cell electric vehicles must be equivalent to or even better than that of current internal combustion engine vehicles, and at the same time, the price is equal to or even lower than that of current internal combustion engine vehicles. The current cost of fuel cell electric vehicles is relatively high. How to impro...
