Methanol steam reforming hydrogen production reactor for fuel cell car

Abstract

A methanol steam reforming hydrogen production reactor for a fuel cell car comprises a casing, wherein a methanol and water solution inlet pipe is arranged at the right end of the casing, a produced hydrogen outlet pipe is arranged at the left end of the casing, and the inside of the casing is divided into a right cavity, a middle cavity and a left cavity by two baffles; an evaporator is arranged in the right cavity; a catalyst is arranged in the middle cavity, a waveguide communicated with the middle cavity is mounted on the pipe wall of the middle cavity, and an electromagnetic pipe is arranged on the waveguide; a condenser is arranged in the left cavity. As a reactant is heated by microwave radiation, the inner side and the outer side of the reactant can be simultaneously heated, the system is uniformly heated, the occurrence of partial high temperature zones and cold points is avoided, the energy efficiency of the system can be improved, and the double effects of energy conservation and emission reduction are realized.

Description

technical field [0001] The invention relates to a reactor, in particular to a methanol steam reforming hydrogen production reactor used for a fuel cell vehicle. Background technique [0002] The automobile industry is the second largest industry after petrochemical industry in the world. At present, almost all automobiles use gasoline and diesel as fuel, which not only consumes a large amount of oil resources, but also the nitrogen oxides and carbon contained in automobile exhaust Hydrides, carbon monoxide, etc. have caused serious air pollution. In order to maintain the sustainable development of the national economy, protect the human living environment and ensure energy supply, governments around the world have invested a lot of manpower and material resources to find various ways to solve these problems. A fuel cell is a high-efficiency power generation device that directly converts the chemical energy of fuel and oxidant into electrical energy through an electrochemica...

AI Technical Summary

Problems solved by technology

The disadvantage is that the heat transfer performance is poor, the volume is generally not easy to reduce, and the effective utilization coefficient of the catalyst may be low in the packed bed of the reactor, and the thermal efficiency of hydrogen production (low calorific value of hydrogen generation / low calorific value of fuel consumption) is not very good. Ideal and other issues

The current methanol steam reforming hydrogen production reactor generally has high system energy consumption, slow system response speed, uneven heating, and problems of "hot spots" and "cold spots" in the reactor
