Answer 1

The correct option is D all of above

There are some downsides of using hydrogen as a fuel :
1.Few filling stations sell hydrogen.
2.Hydrogen must be compressed and liquefied, and then stored in tough, insulated fuel tanks.
3.Atmospheric pollution may be generated during the production of hydrogen.
4.Hydrogen fuel cells do not work at very low temperatures, and they may also require a platinum catalyst (platinum is expensive and prone to contamination by impurities).
