Embodiment 1

[0042] Figure 6 It is a section view viewed from the horizontal direction. It includes an upper half plate 31, a lower half plate 32, a sealing ring 33 partially embedded in the upper surface of the upper half plate, an adhesive 34, a longitudinal fuel main channel 35, a longitudinal oxidant main channel 36, and a penetrating upper half plate located on the upper surface of the upper half plate. Thick flow field 37, flow channel 38 located on the upper surface of the lower half plate, anode diffusion layer 39, membrane electrode 40, cathode diffusion layer 41, upper and lower layers of adhesive tape 42.

[0043] The relationship between the anode diffusion layer 39, the membrane electrode 40, the cathode diffusion layer 41, and the upper and lower layers of adhesive tape 42 is the same as that of the known technology. Covering in the upper and lower directions, the tape plays the role of increasing mechanical strength, sealing, and fixed connection, thus forming a 5-in-1 mem...

Embodiment 2

[0054] like Figure 8 shown. Others are the same as in Embodiment 1, the only difference is that the adhesive 34 is replaced by the sealing ring 45; on the lower surface of the upper half plate and (or) the upper surface of the lower half plate, the corresponding position is provided with a concave cavity for accommodating the sealing ring 45 groove. The sealing ring 45 realizes the sealing between the two half-plates, and the assembly pressing force of the fuel cell realizes the conductive contact.

Embodiment 3

[0056] like Figure 9 shown. Others are all the same as in Example 1, the difference is:

[0057] 1. The flow field 46 that is arranged on the upper surface of the lower half plate and does not penetrate through the thickness of the lower half plate is added. The shape of the flow field 46 is similar to that of the flow field 37, and the positions correspond to each other, thereby increasing the cross-sectional area of ​​the flow field and reducing the resistance of the fuel flow.

[0058] 2. A flow groove 47 arranged on the lower surface of the upper half plate is added, and its position corresponds to the flow groove 38, thereby increasing the cross-sectional area of ​​the flow groove and reducing the resistance of the fuel flow.

Abstract

Disclosed is an anode plate for a fuel cell: A, the anode plate comprises an upper half plate and a lower half plate which are tightly coupled; B, either a flow field which runs through the upper half plate or not or a through hole or a blind hole, or both are arranged on the upper surface of the upper half plate; C, at least the lower surface of the upper half plate or the upper surface of the lower half plate is provided with a flow flute; one end of the flow flute is communicated with the flow field or the hole and the other end is communicated with a main fuel channel. The anode plate has the advantages that sealing is reliable; the anode plate is suitable for batch production and the flow field is flexible in design.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to an anode plate structure of a fuel cell. Background technique [0002] A fuel cell is a device that directly converts chemical energy into electrical energy without combustion. Since it is not limited by the Carnot cycle, its conversion efficiency can easily reach more than 50%, or even more than 70%. In the case of using hydrogen as fuel, the reaction product is pure water without any pollution to the environment. [0003] The voltage of a single fuel cell is low, and the power is also limited, so generally several or even dozens of fuel cells are stacked in series to increase its output voltage and power. In this case, in order to smoothly introduce fuel into each single cell, a longitudinal total channel is generally used, perpendicular to the membrane electrode assembly of each single cell, to introduce fuel into the fuel cell stack, and then lead out the horizontal channel from th...
