How does a basic fuel cell work?
A typical fuel cell works by passing hydrogen through the anode of a fuel cell and oxygen through the cathode. At the cathode, the protons, electrons, and oxygen combine to produce water molecules. As there are no moving parts, fuel cells operate silently and with extremely high reliability.
How does a fuel cell car work?
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.
What is fuel cell explain with example?
A fuel cell is a device that produces electricity through a chemical reaction between a source fuel and an oxidant. The source fuel could be almost anything that can be oxidized, including hydrogen, methane, propane, methanol, diesel fuel or gasoline.
How long does a fuel cell last?
The fuel cell stacks are designed to last the lifetime of the vehicle, about 150,000–200,000 miles. At the end of its lifespan, the fuel cell will be disassembled and the materials recycled, similar to what happens with vehicle components today.
What are the disadvantages of a fuel cell?
What are the Disadvantages of Hydrogen Fuel Cells?
- Hydrogen Extraction.
- Investment is Required.
- Cost of Raw Materials.
- Regulatory Issues.
- Overall Cost.
- Hydrogen Storage.
- Infrastructure.
- Highly Flammable.
What are fuel cells and how do they work?
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions. Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen (usually from air)…
How does a fuel cell produce electricity?
Fuel cells generate electricity through an electrochemical reaction, known as reverse electrolysis. This reaction combines hydrogen and oxygen to form water vapor, heat and electricity.
What is a fuel-cell and how does it work?
If you want to be technical about it, a fuel cell is an electrochemical energy conversion device . A fuel cell converts the chemicals hydrogen and oxygen into water, and in the process it produces electricity. The other electrochemical device that we are all familiar with is the battery.
What is a hydrogen fuel cell and how does it work?
Hydrogen fuel cell. A hydrogen fuel cell is the main source of energy in a hydrogen fuel engine and works like a battery. There is a membrane situated in the middle of the cathode and anode. Hydrogen breaks down when it hits this membrane through a chemical reaction that makes negatively charged electrons and positively charged hydrogen ions.
