燃料电池汽车是电动汽车的一种,其核心部件燃料电池的电能是通过氢气和氧气的化学作用,而不是经过燃烧,直接变成电能。
燃料电池汽车的工作原理是,使作为燃料的氢在汽车搭载的燃料电池中,与大气中的氧发生化学反应,产生出电能发动电动机,由电动机带动汽车中的机械传动结构,进而带动汽车的前后万象轴、后桥等行走机械结构,转动车轮驱动汽车。
核心部件燃料电池采用的能源间接来源是甲醇、天然气、汽油等烃类化学物质,通过相关的燃料重整器发生化学反应间接地提取氢元素;直接来源就是石化裂解反应提取的纯液化氢。
燃料电池的反应结果将会产生极度少的二氧化碳和氮氧化物,这类化学反应除了电能外的副产品主要产生水,因此燃料电池汽车被称为绿色的新型环保汽车。燃料电池的能量转换效率比内燃机要高2~3倍,因此从能源的利用和环境保护方面,燃料电池汽车是一种理想的车辆。
燃料电池汽车的氢燃料能通过几种途径得到。有些车辆直接携带着纯氢燃料,另外一些车辆有可能装有燃料重整器,能将烃类燃料转化为富氢气体。

Fuel Cell Vehicle (FCV) Power Train

The demonstration shows different operating modes of the FCV over one complete cycle: accelerating, cruising, recharging the battery while accelerating and regenerative braking.

 

The FCV Electrical Subsystem is composed of four parts: The electrical motor, the battery, the fuel cell and the DC/DC converter.

 

The FCV Vehicle Dynamics Subsystem models all the mechanical parts of the vehicle.

 

The Energy Management Subsystem (EMS) determines the reference signals for the electric motor drives, the fuel cell system and the DC/DC converter in order to distribute accurately the power from the two electrical sources. These signals are calculated using mainly the position of the accelerator, which is between -100% and 100%, and the measured FCV speed.

 

This demonstration was previously available in SimPowerSystems Version 5.4 (R2011a). The authors of this work are: Olivier Tremblay, Souleman Njoya Motapon, Louis-A. Dessaint (Ecole de Technologie Superieure, Montreal).
