Advantages and disadvantages of fuel cell …

.disadvantages of fuel cell : 1. Nitrogen Dioxide Emission Critics of hydrogen fuel cells argue that although these cells do not emit carbon after burning, they give out nitrogen dioxide and other emissions. Nitrogen dioxide is a toxic gas and can still be harmful when ingested by humans.2. Storage Issues Apart from taking much time to separate the compounds of hydrogen, this element is also a challenge to move and transport. 3.High Cost Aside from having to spend a lot of money to transport hydrogen, the time it takes to break down its elements makes the process expensive as well.

Advantages of fuel cell : 1.Fuel cells have a higher efficiency than diesel or gas engines. 2.Most fuel cells operate silently, compared to internal combustion engines. They are therefore ideally suited for use within buildings such as hospitals. 3.Fuel cells can eliminate pollution caused by burning fossil fuels; for hydrogen fuelled fuel cells, the only by-product at point of use is water. 4.if the hydrogen comes from the electrolysis of water driven by renewable energy, then using fuel cells eliminates greenhouse gases over the whole cycle. 5.Fuel cells do not need conventional fuels such as oil or gas and can therefore reduce economic dependence on oil producing countries, creating greater energy security for the user nation.
