What advantage does fuel cell have over a conventional battery?
Fuel cells allows the production of electricity from fuels without combustion, at a higher efficiency than conventional generation systems and with reduced emissions. Since they operate above room temperature, their heat emissions can be recovered for space heating and domestic hot water applications.
What is the advantage of fuel cell?
Hydrogen fuel cells are cleaner and more efficient than traditional combustion-based engines and power plants. Hydrogen and fuel cells can also be used in mobile applications to power vehicles and mobile power packs. The benefits of fuel cells are: Reduced greenhouse gas emissions.
What are the advantages of a fuel cell compared to an internal combustion engine?
Fuel cells can have an efficiency of over 80 per cent, compared to internal combustion engines that currently operate at around 25 per cent efficiency and power plants at about 35 per cent. This is a huge increase in efficiency and shows that the power going in is creating much more energy.
What are two advantages that fuel cells have when used in the auto industry?
Benefits
- Less Greenhouse Gas Emissions. Gasoline- and diesel-powered vehicles emit greenhouse gases (GHGs), mostly carbon dioxide (CO2), that contribute to climate change.
- Reduced Oil Dependence.
- Less Air Pollutants.
- Vehicle Cost.
- Getting Hydrogen to Consumers.
- Fuel Cell Durability and Reliability.
- Public Education.
What is the problem with hydrogen cars?
The two prime dangers from fuel cell and hydrogen-powered vehicles are the danger of electrical shock and the flammability of the fuel. Fuel cells power vehicles by electro-chemically combining hydrogen gas (H2) and oxygen (O2) from the surrounding air into water (H20) and electrical energy.
Will hydrogen be the fuel of the future?
Hydrogen is the fuel of the future. Hydrogen is an energy carrier that can be used in internal combustion engines or fuel cells producing virtually no greenhouse gas emissions when combusted with oxygen. The only significant emission is water vapor.
Is hydrogen a good source of energy?
Hydrogen, like electricity, is an energy carrier that must be produced from another substance. However, hydrogen is useful as an energy source/fuel because it has a high energy content per unit of weight, which is why it is used as a rocket fuel and in fuel cells to produce electricity on some spacecraft.
