Problems solved by technology

However, the use of graphite as the material of the current collector still has the problem of difficulty in processing. At the same time, the volume of the fuel cell produced is often too large, which is not suitable as a power source for portable electronic products.
The use of metal structures, such as metal mesh structures, as current collectors is beneficial to the miniaturization of fuel cells, but the metal of the metal structure is often corroded by the fuel to produce metal ions, and these metals The ions will cause the reactive functional group to lose the function of transferring hydrogen protons to the proton exchange membrane

Embodiment Construction

[0016] The preferred embodiments of the present invention will be further described in detail below with reference to the attached drawings. The ratio of certain dimensions to other dimensions is exaggerated in order to provide a clearer description and to aid those skilled in the art in understanding the present invention.

[0017] figure 1 is a perspective exploded view showing a preferred embodiment of the fuel cell with chelating agent of the present invention, and figure 2 is to show the invention figure 1 Assembled cross-sectional view. The fuel cell 10 with a chelating agent of the present invention is mainly composed of an anode collector layer 101, a chelating agent (Chelate) layer 103, a membrane electrode group layer 105, a chelating agent layer 103, and a cathode collector layer 107 from top to bottom. made. The anode fuel from the outside, such as methanol solution, flows from the anode collector layer 101 to the anode of the membrane electrode group layer 10...

Abstract

A chelating agent fuel cell, including: the anode collecting layer, the cathode collecting layer and the film electrode group layer; the anode collecting layer at least includes the anode collecting line; the cathode collecting layer at least includes the cathode collecting line; sandwiches the film electrode group layer between the anode collecting layer and the cathode collecting layer. The characteristic of the invention is: uses the chelating agent to form the component of the fuel cell including the metal material, forms the stable disregistry stuff because the metal material erodes and reacts with the creating metal ion.

Description

technical field [0001] The present invention relates to a fuel cell, in particular to a fuel cell combined with a chelating agent, through which the chelating agent (chelate) can react with metal ions separated out in the fuel cell to form a stable complex, such Avoid the adverse effects of these metal ions on the membrane electrode group. Background technique [0002] It is known that a fuel cell is a membrane electrode assembly for performing electrochemical reactions to output power, and the proton exchange membrane is one of the important components of the membrane electrode assembly. In the known fuel cells, graphite, metal structures and the like are usually used as current collecting components for the current collecting function. However, the use of graphite as the material for the current collector still has the problem of difficulty in processing. At the same time, the volume of the fuel cell produced is often too large, which is not suitable as a power source for...
