Abstract
The invention discloses a profiled porous cathode support body material of a direct alcohol fuel cell, which is prepared by the following steps: mesophase carbosphere powder, graphite powder and zinc oxide, calcium oxide, ammonium carbonate, calcium carbonate, magnesia or silicon dioxide are mixed, then performed with injection molding by gel or compression molding and then sintered in embedded carbon. The profiled direct alcohol fuel cell prepared by the obtained profiled porous cathode support body material of a direct alcohol fuel cell in the invention has light weight, small volume, can store fuel and can be carried conveniently.
Description
Technical field:
The present invention relates to a kind of cell cathode support body material.
Background technology:
Methyl alcohol, ethanol and propyl alcohol etc., all can be used as the fuel of direct alcohol fuel battery, wherein, direct methanol fuel cell (Direct methanol fuel cell, DMFC) and directly alcohol fuel cell (Direct ethanol fuel cell, DEFC) because of its used methyl alcohol or ethanol wide material sources, cheap, and its energy utilization efficiency height, eco-friendly operational mode, normal temperature operability and advantage such as be easy to carry, thus outstanding person in the new fuel cell become, in military affairs, communications and transportation, fields such as telecommunications have application prospects.
Traditional direct alcohol fuel battery mainly is made of bipolar plates (mainly adopting graphite or metal to prepare), catalysis-diffusion layer and polymer dielectric film, the shape of fuel cell mostly is flat, and the catalysis-diffusion layer of negative electrode and anode and polymer dielectric film adopt hot pressing mode to be shaped to " three-in-one " membrane electrode assembly.But there is following shortcoming in plate direct alcohol fuel battery: (1) adopts the bipolar plate structure with complex flowfield, manufacturing cost height; (2) prepared miniature and large-scale DMFC weight, volume are big; (3) structure of anode is unfavorable for the discharging of byproduct of reaction (as carbon dioxide), and the structure of negative electrode also is unfavorable for the discharge of byproduct of reaction (as water), influences the stability of battery under long-term work; (4) all adopt liquid methanol to act as a fuel in the DMFC research wherein, have the methanol crossover phenomenon, the DMFC power density reduces greatly; (5) direct fuel-in-storage needs complicated intake line; (6) be not suitable for the mobile phase (fuel) of canned non-liquid state.
The key of abnormally-structured direct alcohol fuel battery is the selection of circular or square cathode support body material.If it is improper to select, not only produce the problem of manufacturing cost costliness, commercial application difficulty, and make cathode support body forming difficulty and performance low easily, be difficult to problems such as coating as producing distortion, cracking, poorly conductive, poor mechanical property, diffusion layer and Catalytic Layer.
Find through literature search prior art, " A tubular directmethanol fuel cell with Ti mesh anode " literary composition that people such as Zhi-Gang Shao deliver on " Journal ofPower Sources " 160 (2006) 1003-1008, this article has been introduced the preparation process of a kind of sleeve cathode and anode.What wherein cathode support body material adopted is the titanium net of tubulose.Successively with the method for immersion coating, prepare diffusion layer and Catalytic Layer on titanium pipe network surface, and then be coated with Nafion solution surperficial the dripping of diffusion layer, this solution becomes polymer dielectric film after solidifying, thereby makes negative electrode.But the employed tubulose titanium net that is used to make cathode support body is provided by the Heggemann company of Germany in this paper, and because of its purity height (＞99.99%) and adopt laser welding technology to make, the cost costliness is so be difficult to popularize use.In addition, because the titanium net mechanical property that adopts is low, easy deformation has influenced the coating of diffusion layer and catalyst layer, has reduced the performance of battery.
Summary of the invention:
The object of the present invention is to provide the relative titanium net of a kind of material that adopts source wide, with low cost, high conductivity, low cost, in light weight, volume is little, the direct alcohol fuel cell profiled porous cathode support body material of nonhazardous and pollution.
