Embodiment Construction

[0025] The present invention will be further described below in conjunction with specific drawings.

[0026] image 3 A schematic structural diagram of a proton exchange fuel cell in the present invention is shown, which is composed of a plurality of interconnected single cells 1 . The single cell 1 is mainly composed of an anode plate 11, a cathode plate 12, and a proton exchange membrane 13, among which the anode plate 11 and the cathode plate 12 are electrochemical reaction sites where the fuel oxidation reaction and the oxidant reduction reaction occur. The key to the quality of the electrode lies in the performance of the catalyst, the material of the electrode and the process of the electrode. The proton exchange membrane 13 is arranged between the anode plate 11 and the cathode plate 12, and the anode plate 11 is connected in parallel to the negative pole of the battery through a wire, and the cathode plate 12 is connected in parallel to the positive pole of the batter...

Abstract

The invention relates to a proton exchange fuel cell. The proton exchange fuel cell comprises a plurality of single cells. The single cell comprises an anode plate, a cathode plate and a proton exchange membrane. A hydrogen channel is formed between the anode plate and the proton exchange membrane, and an oxygen channel is formed between the cathode plate and the proton exchange membrane. The anode plate and the cathode plate are attached opposite to each other, and a plurality of cavities are attached to the back surfaces of the anode plate and the cathode plate, so as to form a coolant channel for a coolant to circulate. A plurality of flowing channels which are arranged in parallel are arranged on the anode plate and the cathode plate. A plurality of pressure-shaped turbulent flow protrusions, arranged in a staggered mode, are arranged at the bottom of each flowing channel along the length direction of the flowing channel. In this way, the hydrogen, the fuel gas and the coolant canbe rolled up and down in the flowing process, so that the flow states of the fluid are converted into turbulent flow through laminar flow, and the reaction speed and the completeness of the fluid fuelare improved; and in addition, the effect of the coolant is further enhanced, so that the temperature rise speed of the cell in the electricity production process is reduced.

Description

technical field [0001] The invention relates to the technical field of power cell manufacturing, in particular to a proton exchange fuel cell. Background technique [0002] Proton exchange membrane fuel cell is a kind of fuel cell, which is equivalent to the "reverse" device of water electrolysis in principle. Its single cell is composed of an anode plate, a cathode plate and a proton exchange membrane. The anode plate is the place where the hydrogen fuel is oxidized, and the cathode plate is the place where the oxidant is reduced. The medium that only allows H+ to pass through, while the electrons lost by H2 pass through the wire. [0003] The above-mentioned anode plate, cathode plate and proton exchange membrane are interlocked to form hydrogen channels, oxygen channels and coolant channels. The specific shape, structure and direction of the above three channels are crucial to the power generation efficiency of the battery. influences. For this reason, Chinese inventio...
