Microwave reactor for preparing loaded fuel cell catalyst

Abstract

The invention relates to a microwave reactor for preparing a loaded fuel cell catalyst. The microwave reactor comprises a reactor main body, a microwave reaction system, a microwave controlling and adjusting system, a temperature adjusting system and a temperature control system, wherein at least one reactor cavity is formed in the reactor main body; the microwave reaction system is arranged on the reactor; an internal member can be arranged in the cavity; at least one reactor main body is arranged; and the cavity uses the concept of a shell and tube reactor for reference; and in the microwave reaction system, microwaves are directly introduced into a reaction medium through a microwave guide pipe or act in the form of external microwaves. The catalyst with high performance is obtained by making use of the advantage of rapid and uniform heating of microwaves together with the characteristic of the shell and tube reactor, improving the reactor and optimizing and promoting the dispersion and positioning of active ingredients of the catalyst on a carrier. The reactor disclosed by the invention has the characteristics of low energy consumption, wide application range, reasonable structure, easy management, wide use and the like.

Description

technical field [0001] The invention belongs to the field of fuel cell catalyst preparation and relates to a novel catalyst preparation device. Background technique [0002] A fuel cell is a device that converts chemical energy in fuel and oxidant directly into electrical energy. Because the energy conversion process is not limited by the Carnot cycle, fuel cells have become the focus of attention in both academia and industry. More importantly, with the continuous economic and social development in recent years, energy shortages and environmental pollution have become increasingly serious. Fuel cells have the advantage of low or even "zero emissions" and will become the preferred choice for future automobiles, distributed power stations and portable appliances. Ideal replacement power supply. In recent years, the development direction of vehicle fuel cell technology has gradually become clear, and proton exchange membrane fuel cell has been identified as the most suitable...
