Embodiment Construction
[0027] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0028] In addition, the descriptions involving "first", "second" and so on in the present invention are only for descriptive purposes, and should not be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. In addition, the technical solutions of the various embodiments can be combined with each other, but it must be based on the realization of those ski...

Abstract
A fuel cell for heating devices based on high-efficiency waste heat utilization composite pole plates, including two composite pole plates and membrane electrodes, the membrane electrodes are arranged between the two composite pole plates, the composite pole plates include heat sinks and clamps, and the heat sinks are inlaid In the fixture, the heat sink includes a bottom plate, and there are several fins in a linear array on one side of the bottom plate, and the fins are located on the side opposite to the membrane electrode; the present invention constitutes a The heat sink with heat dissipation function, the heat sink is embedded in the fixture, forming a composite plate with both traditional plate function and heat dissipation function. By integrating the present invention with electronic devices, on the one hand, the electronic devices can be To dissipate heat, on the other hand, the heat generated when the electronic devices are working can be absorbed by the present invention, which is used to increase the working temperature of the present invention itself, and then improve the performance of the fuel cell of the present invention.
Description
technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a fuel cell for heating devices based on high-efficiency waste heat utilization composite pole plates. Background technique [0002] A fuel cell is an electrochemical reaction power generation device, which directly converts chemical energy into electrical energy without going through a heat engine process, and is not limited by the Carnot cycle. Therefore, it has high energy conversion efficiency, no noise, and no pollution. It is becoming an ideal One of the energy utilization methods. At the same time, with the continuous maturity of fuel cell technology and the abundant natural gas source provided by the West-East Gas Pipeline Project, there is a broad prospect for the commercial application of fuel cells. [0003] The direct methanol fuel cell belongs to the category of proton exchange membrane (PEMFC), which directly uses methanol aqueous solution or steam m...
