What are the outputs of a hydrogen fuel cell?
Cell outputs generally range from 50 to 250 kW. The solid, flexible electrolyte will not leak or crack, and these cells operate at a low enough temperature to make them suitable for homes and cars. But their fuels must be purified, and a platinum catalyst is used on both sides of the membrane, raising costs.
How is electricity generated with a hydrogen fuel cell?
A fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode. In a hydrogen fuel cell, a catalyst at the anode separates hydrogen molecules into protons and electrons, which take different paths to the cathode. The electrons go through an external circuit, creating a flow of electricity.
How does a hydrogen fuel cell work?
Hydrogen fuel cells produce electricity by combining hydrogen and oxygen atoms. The hydrogen reacts with oxygen across an electrochemical cell similar to that of a battery to produce electricity, water, and small amounts of heat. Many different types of fuel cells are available for a wide range of applications.
What is the main problem for hydrogen as fuel?
The key challenges include: Weight and Volume. The weight and volume of hydrogen storage systems are presently too high, resulting in inadequate vehicle range compared to conventional petroleum fueled vehicles.
How much voltage does a hydrogen fuel cell produce?
0.5 V to 0.8 V
A typical hydrogen fuel cell produces 0.5 V to 0.8 V per cell. To increase the voltage individual cells can be connected in series. This arrangement is called a fuel cell stack.
Can hydrogen fuel cell cars explode?
Hydrogen used in the fuel cells is a very flammable gas and can cause fires and explosions if it is not handled properly.
How does a fuel cell animation work?
Home ยป Fuel Cell Animation. This fuel cell animation demonstrates how a fuel cell uses hydrogen to produce electricity, with only water and heat as byproducts. Hydrogen fuel cell vehicles emit approximately the same amount of water per mile as conventional vehicles powered by internal combustion engines.

What is the anode and cathode in hydrogen fuel?
Hydrogen fuel (H 2) is channeled to the anode, where the catalyst separates the hydrogen’s negatively charged electrons from the positively charged protons. The membrane allows the positively charged protons to pass through to the cathode, but not the negatively charged electrons.
How many fuel cells are in a stack?
A typical fuel cell stack may consist of hundreds of fuel cells. Fuel cells are a flexible technology and have a broad range of applications. Fuel cells can be used to provide propulsion or auxiliary power for transportation applications including cars, trucks, buses, trains, ships, and submarines.
