普通汽车向环境排放的二氧化碳约为35磅。轿车和卡车使用800万桶石油。交通运输造成了13.5%的环境污染。这些车辆产生的空气污染物包括甲烷、碳单氧化物、氮氧化物等(Stern, 2014)。其主要原因是传统汽车利用化石燃料的行动。相比之下，氢动力汽车需要更少的能源(Stern, 2014)。氢动力汽车将造成更少的环境足迹。它利用氢和氧来产生电能、热能和其他能源。氢燃料电池的生产依赖于可再生能源。氢燃料电池在阳极和阴极方面与电池相似。尽管如此，它不会像普通电池那样随着时间的推移而退化(Eberle, Muller & von Helmolt 2012;8781页)。它有一个系统，可以为生产和合成自然补充能量。为氢动力汽车生产能源不需要化石燃料。它比柴油或燃气发动机的效率更高，并且与之相比产生的噪音更小(Lee, Speight & Loyalka 2014 p. 23)。
燃料电池的维护相对较少。PEMFC和DMFC燃料电池汽车是军事行动的理想选择(Barbir 2012;39页)。尽管有这些优点，氢动力汽车不能大规模生产。目前，还没有大规模生产氢动力汽车的基础设施。这段时间被认为是过渡期(Briggs, Webb & Wilson 2015)。由于这个事实，制造氢动力汽车和随后的燃料电池是非常昂贵的。有一些制造和维护问题需要解决。氢基本上是一种高度易燃的物质。它需要足够的基础设施来维护这方面(Briggs, Webb & Wilson 2015)。氢燃料电池的安全问题应该考虑到氢动力汽车的生产。尽管氢动力汽车实际上不需要化石燃料，但氢和氧的分离仍然依赖于传统燃料。
Average car emits about 35 pounds of CO2 into environment. Cars and trucks use 8 million barrels of oil. Transportation along contributes to 13.5% of environmental pollution. Air pollutants from these vehicles are Methane, Carbon Mono Oxide, Nitrogen Oxide compounds, to name a few (Stern, 2014). Primary reason for this is conventional automobile utilizing fossil fuels for its action. Hydrogen Powered vehicles require lesser energy in comparison (Stern, 2014). Hydrogen powered vehicles will cause lesser environmental footprint. It utilizes Hydrogen and Oxygen for its production of electricity, heat and other sources of energy. For the production of energy hydrogen fuel cells depend on renewable sources of energy. Hydrogen Fuel cells are similar to the battery cell in terms of having an anode and cathode. Nonetheless, it does not degrade over time like regular battery cells (Eberle, Müller & von Helmolt 2012; p 8781). It has a system that naturally replenishes energy for the production and composition. Fossil fuels are not required for the production of energy for Hydrogen powered vehicles. It has higher efficiency than diesel or gas engines, and it has been found to produce lesser noise in comparison (Lee, Speight & Loyalka 2014 p. 23).
Maintenance of fuel cells is comparatively lesser. PEMFC and DMFC fuel cells vehicles are ideal for military operations (Barbir 2012; p 39). In spite of these advantages hydrogen powered vehicles cannot be produced on a large scale. Currently, there is no infrastructure for large-scale production of hydrogen-powered vehicles. This period is considered to be the transition period (Briggs, Webb & Wilson 2015). Owing to this fact, it is very expensive to manufacture hydrogen-powered vehicles and subsequent fuel cells. There are some manufacture and maintenance issues that need to be addressed. Primarily, Hydrogen is a highly flammable material. It requires adequate infrastructure to maintain this aspect (Briggs, Webb & Wilson 2015). Safety issues from hydrogen fuel cells should be factored in for the production of hydrogen-powered vehicles. Even though hydrogen powered vehicles do not actually require fossil fuels, there is dependence on traditional fuels for separation of hydrogen and oxygen.
