代写论文：氢气燃料
用于燃料电池的氢气（H2）可以通过涉及生物质，化石燃料以及水电解伴随电力的各种国内资源来生产。气化可用于此目的，其中合成气，一氧化碳，氢气混合物和少量二氧化碳是通过使天然气与高温下的蒸汽反应而产生的。一氧化碳与水反应产生额外的氢气（Collejas等，2014）。氢气是最轻的气体，因为一公升的氢气在大气压下的重量仅为90毫克，这意味着它比空气轻11倍。氢气可以以气态，液态和固态三种形式储存。但是，固体形式不提供有效的储存，因为以气态形式的高压储存是有效的。

目前，复合材料储罐和气瓶采用重量轻的材料制造，以便在700巴的压力下储存氢气，使5公斤氢气储存在125升储罐内（Dutta，2014）。据发现，硼氢化钠（NaBH 4）可以吸收大量的氢气并且可以在4MPa的温和压力条件下起到像海绵一样的释放作用，用于浸泡气体，但需要储存在镍壳中。当汞达到350时，氢在50摄氏度释放（Collejas等，2014）。氢气可以在压力下通过铂催化剂填充到燃料电池中，并且将其分成两个离子和两个电子。因此，电子为电模型提供动力，同时通过离开车辆的氢和氧的组合形成水作为蒸汽。

Hydrogen (H2) for fuel cells can be produced through diverse range of domestic resources involving the biomass, fossil fuels along with water electrolysis accompanied with electricity. Gasification can be used for this purpose wherein the synthesis gas, carbon monoxide, hydrogen mix and carbon dioxide in small amounts are created through reacting the natural gas with steam at high temperature. The carbon monoxide’s reacts with water for the additional hydrogen production (Collejas et al., 2014). Hydrogen is the lightest gas due to which one litre of hydrogen weights merely 90 mg in atmospheric pressure implying that it is 11 times than lighter than the air. The hydrogen can be stored in three forms, gaseous, liquid and solid. However, the solid form does not provide efficient storage due to which high pressure storage in gaseous form is efficient.

Presently, composite tanks and cylinders are being made with light weight material to store hydrogen at the 700 bar pressure allowing the 5 kg of hydrogen to be stored within a 125 litre tank sizes (Dutta, 2014). It is found that sodium borohydride (NaBH4) can absorb large amount of hydrogen and can enable its release under mild pressure conditions of 4 MPa acting like a sponge for soaking the gas but requires storage in a nickel shell. The hydrogen is released at 50 degrees Celsius when the mercury reached 350 (Collejas et al., 2014). The hydrogen can be filled in the fuel cells through a platinum catalyst under pressure, and this splits it in two ions and two electrons. Hence, the electrons power the electric model while the water is formed through the combination of hydrogen and oxygen exiting the vehicle as steam.
