ii) Clean – Fuel cells work with little to no emissions, the only byproducts being electricity, heat and water. They are thus, much cleaner than traditional power generation, producing 97% less nitrogen oxide emissions than the thermal power plants.

The main advantages of a hybrid are that it should consume less fuel and emit less CO2 than a comparable conventional petrol or diesel-engined vehicle. Hybrid car owners also get extra benefits in the shape of lower first year road tax and company car tax, as well as possibly avoiding congestion charges.

Wet Cell Advantages For the amount of power that they supply, and their durability, wet cell batteries are fairly affordable. If properly maintained, wet cell batteries also have a high number of charge-discharge cycles. They are also less likely than other batteries to suffer damage from overcharging.

They can reduce emissions and even save you money. Fueling with electricity offers some advantages not available in conventional internal combustion engine vehicles. Because electric motors react quickly, EVs are very responsive and have very good torque.

Fuel cell vehicles use hydrogen gas to power an electric motor. Unlike conventional vehicles which run on gasoline or diesel, fuel cell cars and trucks combine hydrogen and oxygen to produce electricity, which runs a motor.

Fuel cells can use hydrogen produced from renewable electricity sources or be powered by other fuels, such as natural gas. They are basically emission-free, quiet and efficient, and very reliable. Although they remain expensive, a 30 percent federal tax credit combined with state incentives reduces purchase costs.

A fuel cell produces electricity by means of electrochemical reactions between a fuel, typically hydrogen, and the oxygen in the air. During the reaction, hydrogen and oxygen combine to produce electrical energy and harmless water vapor as a byproduct.

Until recently, the platinum catalyst that splits the hydrogen into an ion and an electron has been prohibitively expensive. Up to a few years ago, hydrogen fuel cells cost around $1000 for every kilowatt of power they generated – or around $100,000 per car.
