1、fuel cell electric vehicles using hydrogen and oxygen in the air under t he action of catalyst hitches in a fuel cell electrochemical reaction to pr oduce electricity, and as the main source of power drive car.fuel cell electric vehicle is in essence a kind of electric cars, in body, p ower transmis

2、sion system, control system, etc., the fuel cell electric veh icle and general electric car basic same, the main difference is that the principle of power battery is different. generally speaking, the fuel cell i s through electrochemical reactions convert chemical energy into electr icity, electroc

3、hemical reaction required reductant with hydrogen, oxyge n oxidant is used, so the earliest development of fuel cell electric vehicl e is more directly using hydrogen fuel, hydrogen storage can use liquefi ed hydrogen, compressed hydrogen or metal hydride hydrogen storage , etc.pure fuel cell car fu

4、el cell is only a source of power, the car all the echo power of fuel cell. at present, a lot of fuel cell vehicles driven by mixed form, on the basis of the fuel cell, increases a set of battery or super ca pacitor as another source of power. the main structure: energy control unit, air compressor,

5、 fuel cell stack, high pressure hydrogen storage bo ttle, power battery and motor. high pressure hydrogen storage bottle pr ovided with fuel, and outside of the power supply, power battery for car acceleration, climbing and running at a high speed. slide on the vehicle , the energy control unit will

6、 drive motor into generator, which will be pa.rt of the vehicle kinetic energy into electrical energy to power the batter y. that is to say after using hybrid form, not only can use smaller power battery system, can also be the basis of kinetic energy recovery. also can be a fuel cell system operati

7、on condition is relatively stable, improv e the efficiency of fuel cell system and life expectancy.燃料電池電動(dòng)汽車(chē)是利用氫氣和空氣中的氧在催化劑的作用下在燃料電池中經(jīng)電化學(xué)反應(yīng)產(chǎn)生的電能，并作為主要?jiǎng)恿υ打?qū)動(dòng)的汽車(chē)。燃料電池電動(dòng)汽車(chē)實(shí)質(zhì)上是電動(dòng)汽車(chē)的一種， 在車(chē)身、動(dòng)力傳動(dòng)系統(tǒng)、 控制系統(tǒng)等方面，燃料電池電動(dòng)汽車(chē)與普通電動(dòng)汽車(chē)基本相同， 主要區(qū)別在于動(dòng)力電池的工作原理不同。 一般來(lái)說(shuō)， 燃料電池是通過(guò)電化學(xué)反應(yīng)將化學(xué)能轉(zhuǎn)化為電能， 電化學(xué)反應(yīng)所需的還原劑一般采用氫氣， 氧化劑則采用氧氣， 因此最早開(kāi)發(fā)的燃料電池電動(dòng)汽車(chē)多是直接采用氫燃料， 氫氣的儲(chǔ)存可采用液化氫、 壓縮氫氣或金屬氫化物儲(chǔ)氫等形式。純?nèi)剂想姵剀?chē)只有燃料電池一個(gè)動(dòng)力源，汽車(chē)的所有功率附和都有燃料電池承擔(dān)。目前燃料電池汽車(chē)多采用混合驅(qū)動(dòng)形式， 在燃料電池的基礎(chǔ)上， 增加了一組電池或超級(jí)電容作為另一個(gè)動(dòng)力源。主要結(jié)構(gòu)有：能量控制單元，空氣壓縮機(jī)，燃料電池堆，高壓儲(chǔ)氫瓶，動(dòng)力電池組，電動(dòng)機(jī)。高壓儲(chǔ)氫瓶提供燃料，動(dòng)力電池組提供而外的功率，讓車(chē)加速、爬坡和高速運(yùn)行。在車(chē)輛滑行時(shí)，能
