Method for manufacturing fuel cell capable of synthesizing acetic acid simultaneously

Abstract

The invention discloses a method for manufacturing a fuel cell capable of synthesizing acetic acid simultaneously, which comprises the following main steps of: adding ethylene diamine tetraacetic acid (EDTA) serving as a complexing agent, formaldehyde serving as a reducing agent and solution of PdCl2 or PdCl2 and RuCl3 into a hydrothermal reactor, performing heating reaction, and cooling to obtain PdRu or Pd nanometer catalyst particles; mixing the PdRu or Pd nanometer catalyst particles and VulcanXC-72 to obtain carbon-loaded PdRu or Pd catalyst particles; mixing the carbon-loaded catalyst particles and polytetrafluoroethylene uniformly in ethanol, and performing ultrasonic dispersion to form paste; coating the paste on a stainless steel mesh uniformly, drying and pressurizing to obtain Pd and PdRu nanometer porous electrode plates; and assembling the fuel cell by using the Pd electrode plate as a cathode and the PdRu electrode plate as an anode, wherein electrolyte of an anode chamber and electrolyte of a cathode chamber are respectively sodium hydroxide solution of the ethanol and sulfuric acid solution of hydrogen peroxide and are separated by a positive ion membrane. The method is simple and has readily available materials, and the acetic acid can be synthesized while the fuel cell is used.

Description

A kind of manufacturing method of fuel cell capable of synthesizing acetic acid simultaneously technical field The invention belongs to the field of fuel cells, and in particular relates to a method for preparing nanoporous Pd-Ru and nanoporous Pd electrocatalysts and assembling an ethanol / hydrogen peroxide fuel cell capable of simultaneously synthesizing acetic acid. Background technique Direct Alcohol Fuel Cell (DAFC) has outstanding advantages such as small size, light weight, simple manufacture, and convenient use, and is especially suitable as a supporting power source for portable electronic devices. However, due to methanol’s easy permeation, low operating temperature, flammability, and volatile characteristics, and methanol has certain toxicity, the direct methanol fuel cell using methanol as fuel has great unsafety in the field of mobile power, so Finding new liquid fuels to replace methanol has important practical significance. As a common chemical substance, et...
