氢燃料电池汽车(FCEV)在长途运输、重型车辆应用中优势明显,特别是加氢快速、续航里程长。宝马集团副总裁尤尔根·古尔德纳表示,BMW i Hydrogen NEXT的燃料电池能从氢气和空气中的氧气反应产生125千瓦(170马力)的电能,仅排放水蒸气。车辆配备的电力转换器能适配电动系统和峰值功率电池的电压,后者利用制动和燃料电池能量。车上的700bar储氢罐共可存六公斤氢气,确保长续航,且加氢快速,只需三至四分钟。第五代eDrive单元也整合到了该车型中。
Mohammed Shafi曾在全球商业平台Brink上发表一篇比较了BEV和FCEV可行性的论文。Shafi表示,FCEV在环保方面优于BEV和内燃机车辆,生产过程更清洁,原材料需求少,且更容易回收。不过,当前FCEV的压缩氢气罐体积较大,是一个技术缺陷。未来可能用氢金属或非金属氢化物替代重型氢气罐,但氢气蒸发仍是需要解决的技术难题。
