Fuel Cells

Fuel Cells convert an electrochemical reaction to electticity. There are applications that are sationary, portable and those used in transportation. All Fuel Cells are composed of an anode, cathode and electrolyte and are typically characterized by the composition of he electrolyte. The most common is the Proton Exchange Membrane (PEM). Others are Phospheric Acid (PAFC), Solid Oxide (SOFC), Molten Carbonate (MCFC) and Direct Methane (DMFC).

What waste is produced from a fuel cell?

The waste produced from a fuel cell depends on the type of fuel cell. Common waste materials include heat, water, and small amounts of carbon dioxide. Some fuel cells may also produce small amounts of pollutants or byproducts that need to be managed.

What evidence does the author provide to support the claim that fuel cell vehicles may not provide an answer to current energy problems?

What author? What article? Please restate the question. It is lacking in information necessary to properly answer it.

What does fuel cell do in stick RPG 2?

The Fuel cell upgrades the flamethrower, for the flamethrower you need a leafblower and somethingelse

Is Daniell cell a fuel cell?

The Daniell cell (Daniel cell) was invented in 1836 by John Frederic Daniell, a British chemist and meteorologist, and consisted of a copper pot filled with a copper sulfate solution, in which was immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode. As such it is more akin to a battery than a fuel cell.

Does the government offer incentives to use hydrogen fuel cell generators as a power source?

Yes, many institution will provide incentives for any renewable energy and hydrogen is one of them. Check your state first then the federal government to see what your entitled to.

Do oakley fuel cells fit on large faces?

In my opinion yes! i have a large face and i usually wear gascans but i recently purchased some Fuel cells the biggest difference is the side ear pieces are thicker on the fuel cells. I HOPE THIS HELPED

Where do you use fuel cell on stick rpg 2?

You use it to upgrade the flamethrower, which you have to make from a leaf blower, which you get from the hardware store, which is restricted to the Director's Cut.

Is hydrogen based fuel cells better than nuclear power?

Probably, but the technology for ordinary day usage just isn't there yet.

Nuclear power can be safe. We just need to think of all the possible scenario's that could happen. The Japanese built the nuclear plant to sustain an earthquake much larger (and it did), but they didn't see the fact that the tsunami flooded the generator rooms and rendered the generators useless. Had they made the generator structure so ocean water could not penetrate or move the structure, they would have been fine.

Is true regarding hydrogen fuel cells and hydrogen?

the amount of mass that disappears in the fusion of two hydrogen atoms is morte than the amount of mass that dissappears when two atoms are fully used in a cell

What are the emission products of fuel-cell powered vehicles?

Water vapor is the sole byproduct of fuel cell electric vehicles.

Why hydrogen is mostly used in fuel cells?

A hydrogen vehicle is an alternative fuel vehicle that uses hydrogen as its onboard fuel for motive power. The term may refer to a personal transportation vehicle, such as an automobile, or any other vehicle that uses hydrogen in a similar fashion, such as an aircraft. The power plants of such vehicles convert the chemical energy of hydrogen to mechanical energy either by burning hydrogen in an internal combustion engine, or by reacting hydrogen with oxygen in a fuel cell to run electric motors. Widespread use of hydrogen for fueling transportation is a key element of a proposed hydrogen economy.

How are fuel cells categorized?

explain how fuel cells are commonly categorized

Are hydrogen fuel cell car dangerous?

The most likely spot for a hydrogen fuel tank on any possible car that will be built is going to be on the top of the car. This would prevent you from becoming part of the fuel burn in an accident. The fuel would flow up and away from the people involved.

They would not be any more dangerous because of the fuel they were carrying. The technology may still be unlikely to go into this direction because they provide no real advantage at the moment over gas or diesel powered cars. Hydrogen would not provide any real savings in terms of fossil fuel reduction or savings from a pollution standpoint.

The current method of making hydrogen is to strip it from natural gas.

Do hydrogren fuel cells really improve fuel mileage in cars?

no, they just mean that the engine has a supply of hydrogen to run on rather than any other fuel

Evaluate the use of primary and secondary cells for mobile electronic units such as a laptop MP3 player torch etc and a hydrogen fuel cell that could be used in a car?

Primary cells, such as alkaline batteries, are typically used in mobile electronic devices like laptops and MP3 players due to their convenience and portability, providing immediate power but limited lifespan. Secondary cells, or rechargeable batteries like lithium-ion, are favored for their longevity and the ability to recharge, making them ideal for devices that require frequent use. In contrast, hydrogen fuel cells offer a promising alternative for vehicles, providing longer ranges and faster refueling compared to traditional batteries; however, they face challenges in infrastructure and production efficiency. Ultimately, the choice between these energy sources depends on the application, with each having distinct advantages and limitations.

Electric Car vs Hydrogen Fuel Cell Cars pros and cons?

Neither car is available and most likely will not be for some time, if ever. Fuel cell technology is probably closer to a reality. The major disadvantage is that they produce no fuel savings and are not a positive for our environment. Hydrogen is derived by stripping it from natural gas. The net result is that we use fossil fuel to power the fuel cell car.

What are the advantages of fuel cells?

The most important advantage of fuel cells is that their only byproduct is water, and of course discarded parts. The disadvantage is that the hydrogen used in them has to be electrolyzed from water or found in some other way. Because of the law of conservation of energy, fuel cells do not produce energy, they only store it.

What can fuel cells be used for?

Anything that needs electricity can be fed from a fuel cell.
