Commercial vehicle with fuel cell adopting methanol reforming for hydrogen production

Abstract

The invention relates to the technical field of commercial vehicles, in particular to a commercial vehicle with fuel cell which adopts methanol reforming for hydrogen production. The commercial vehicle comprises a chassis, an electric driving system, a methanol water tank, a system for hydrogen production through methanol reforming, a fuel cell system and a buffer tank, wherein the methanol watertank is used for storing a methanol solution; the system for hydrogen production through methanol reforming is used for allowing the methanol solution to undergo a reaction so as to generate hydrogen;the fuel cell system is used for converting the energy of a hydrogen reaction into electric energy and driving the electric driving system to work; and the buffer tank is used for storing redundant low-pressure hydrogen. Hydrogen used by the commercial vehicle is prepared from the methanol solution, so various safety problems, use and maintenance problems, cost problems, driving range problems and the like caused by high-pressure hydrogen storage can be effectively solved; a methanol fuel is wide in source, mature in production process and low in price; and the aqueous methanol solution is small in occupied space and high in hydrogen storage density, a driving range can be increased by increasing an encasement volume, and the use requirements of large-tonnage commercial vehicles are better met.

Description

technical field [0001] The invention relates to the technical field of commercial vehicles, in particular to a methanol reforming hydrogen production fuel cell commercial vehicle. Background technique [0002] Hydrogen fuel cell commercial vehicles have the advantages of environmental protection and energy saving. However, there are few hydrogen refueling stations, and the cost of building stations is high. Moreover, it is difficult to "produce, store, transport, and charge" high-pressure hydrogen, and the operation and maintenance costs and use costs are high. However, the methanol reforming hydrogen production technology route can well solve various problems caused by high-pressure hydrogen storage, and has a good application prospect especially for large-tonnage commercial vehicles for road transportation. At present, methanol reforming hydrogen production technology is mainly used in the backup power supply of communication base stations, and the vehicle-level applicatio...

AI Technical Summary

Problems solved by technology

At present, methanol reforming hydrogen production technology is mainly used in the backup power supply of communication base stations, and the vehicle-level application is not yet mature. It is mainly used in passenger cars and small-tonnage urban logistics vehicles, etc., which cannot meet the needs of large-tonnage commercial vehicles.
