which of the following would be considered a fuel cell course hero

Why am I against the immediate introduction of fuel-cell cars?

Include likely points of objection from those with opposing views (such as environmental and economic impacts) as well as counterarguments to those objections. I am against the immediate introduction of fuel-cell cars because they are not durable enough and are too expensive. Fuel-cell cars are not durable enough to compete with gasoline vehicles.

How much power does a stack of fuel cells produce?

If a stack of 40 solid oxide fuel cells in series generates 1,000 W of power, and each cell contributes equally to the power of the stack, how much power does each cell contribute? A series stack of alkaline cells produces 6 kW of power. If each cell contributes 14.5 W, how many cells are in the stack?

How do companies encourage people to use fuel cell cars?

A company that is concerned about the environment wants to encourage the use of their fuel cell cars, so they are putting together information to help sell the cars. They want to be sure their material is accurate.

Can fuel-cell cars compete with gasoline vehicles?

Fuel-cell cars are not durable enough to compete with gasoline vehicles. Gasoline vehicles have at least a 150,000-mile lifetime, while fuel-cell vehicles only have a lifetime of 75,000.

Which of the following is a fuel cell fuel?

HydrogenIn the fuel cell, Chemical energy is converted to Electrical energy. Hydrogen and oxygen gases are used in fuel cell along with water, heat.

Is a battery considered a fuel cell?

Comparing a battery and a fuel cell may be confusing as both can be used as sources of power, but in different ways. In battery electric vehicles, batteries store and deliver energy to the powertrain. A fuel cell electric vehicle generates electricity using hydrogen as fuel, and also delivers energy to the powertrain.

What is a fuel cell quizlet?

A fuel cell is an. electrical cell. Fuel cells produce electrical energy efficiently by being supplied with. fuel and oxygen and using the energy from their reaction to produce the electrical energy.

What type of cell is a fuel cell?

Polymer electrolyte membrane (PEM) fuel cells—also called proton exchange membrane fuel cells—deliver high power density and offer the advantages of low weight and volume compared with other fuel cells.

Which of the following is not a fuel cell?

Which of the following is not an example of a fuel cell? Explanation: Hydrogen-oxygen cell, methyl-oxygen-alcohol cell and propane-oxygen cell are some of the examples of fuel cells. Hexanone-oxygen cell is not an example of a fuel cell.

Which is used as the fuel for cells quizlet?

Hydrogen fuel cells generate electricity from transforming chemical energy in hydrogen to electrical energy. Their only byproduct is water and water vapour. A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water.

Are hydrogen fuel cells quizlet?

Hydrogen fuel cells and batteries are both electro chemical cells. They each have two electrodes in contact with a material that can conduct ions, called an electrolyte. A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. Fuel cells are often compared to batteries.

What is the function of a fuel cells?

A fuel cell uses the chemical energy of hydrogen or other fuels to cleanly and efficiently produce electricity. If hydrogen is the fuel, the only products are electricity, water, and heat.

Why are fuel cell vehicles better for the environment?

Some may say that fuel-cell vehicles are better for the environment, because of the reduced amount of fossil fuels and less air pollutants produced, but it all comes at a cost. In order to fuel your fuel-cell vehicle you must be able to obtain hydrogen for the vehicle.

How long do fuel cell vehicles last?

Gasoline vehicles have at least a 150,000-mile lifetime, while fuel-cell vehicles only have a lifetime of 75,000. Fuel-cell vehicles are only half as durable as gasoline vehicles, which means you would have to buy 2 fuel-cell vehicles to last just as long as one gasoline vehicle.

Why are fuel cell cars bad?

I am against the immediate introduction of fuel-cell cars because they are not durable enough and are too expensive . Fuel-cell cars are not durable enough to compete with gasoline vehicles. Gasoline vehicles have at least a 150,000-mile lifetime, while fuel-cell vehicles only have a lifetime of 75,000. Fuel-cell vehicles are only half as durable as gasoline vehicles, which means you would have to buy 2 fuel-cell vehicles to last just as long as one gasoline vehicle. Fuel-cell vehicles are not on the reasonable price side either. Fuel-cell vehicles are more expensive than gasoline vehicles and hybrids. Saving the money to buy a gasoline vehicle or hybrid instead of a fuel-cell vehicle, could be used as part of maintenance of your car, in case it breaks down, which all cars do. Some may say that fuel-cell vehicles are better for the environment, because of the reduced amount of fossil fuels and less air pollutants produced, but it all comes at a cost. In order to fuel your fuel-cell vehicle you must be able to obtain hydrogen for the vehicle. There are not many public stations available in the state or the country, which would limit the amount of coverage the vehicle has.

How many kW does a series stack of alkaline cells produce?

A series stack of alkaline cells produces 6 kW of power. If each cell contributes 14.5 W, how many cells are in the stack? (Round to the nearest whole number.)

Is a fuel cell car cheaper than a gasoline car?

Fuel-cell vehicles are not on the reasonable price side either. Fuel-cell vehicles are more expensive than gasoline vehicles and hybrids. Saving the money to buy a gasoline vehicle or hybrid instead of a fuel-cell vehicle, could be used as part of maintenance of your car, in case it breaks down, which all cars do.

What is the classification for the drug of choice to control itching, sneezing, and rhinor?
