How many volts does a fuel cell produce?
According to the US Department of Energy, one fuel cell produces around 0.5 to one volt of electricity.
What is the only waste product of a fuel cell?
How do fuel cells generate electricity * 1 point?
Fuel cells typically generate electricity using hydrogen and emit only water and heat. For polymer electrolyte membrane (PEM) fuel cells, hydrogen is fed into one side of the fuel cell, and oxygen is fed into the other. A single fuel cell produces about one volt of power.
What emission does a fuel cell produce?
Fuel cell electric vehicles emit only water vapor and warm air, producing no tail-pipe emissions. Similar to electricity, hydrogen is an energy carrier that can be produced from various feedstocks. These feedstocks and production methods should be considered when evaluating hydrogen emissions.
What are the disadvantages of using hydrogen fuel cells?
Disadvantages of using fuel cells in cars hydrogen is in the gas state at room temperature and pressure, so it is difficult to store in the car. fuel cells and electric motors are less durable than petrol engines and diesel engines, so they are not so long-lasting. fuel cells are very expensive.
What is the downside of using hydrogen as fuel for cars?
It’s also the safest form of energy to perform such an energy-intensive task. Hydrogen energy is, in fact, 3 times more potent than gasoline and other fossil-based sources of fuel. The downside to using hydrogen in cars is that it’s practically difficult to store in cryogenic or high-pressure tanks.
What are the advantages and disadvantages of a hydrogen fuel cell?
Hydrogen Fuel Cell Advantages and Disadvantages in Material…
- Hydrogen Fuel Cell Technology.
- Advantage: High Energy Density Improves Productivity.
- Disadvantage: The Use of Fossil Fuels in Hydrogen Production.
- Disadvantage: Hydrogen Storage and Transportation.
- Disadvantage: Fuel Cell Efficiency.
Are fuel cells safe?
They aren’t tied to an electric plug. They produce zero emissions from the tailpipe and can deliver 300 miles or more per tank of fuel. They can be refilled as fast — or faster — than a conventional car with a 15-gallon gas tank. After extensive testing, researchers say they are as safe to drive as gasoline cars.
