The efficiency of the combustion depended on the fuel to oxygen ratio. If mixture was fuel lean the combustion reaction would produce less soot and smoke. If the mixture was fuel rich‚ an incomplete combustion reaction occurred and it produced plenty of soot and smoke. The controlled

No pollution: A great benefit of using Hydrogen fuel cells is that they give off no pollution‚ and in fact produce pure water as a byproduct. Even though currently engineers are concentrating on producing hydrogen from natural gas‚ it will be for a short-term. Scientists are planning to have renewable environmentally-friendly ways of producing hydrogen in the future. Efficiency: Fuel cells generate electrical power
