What is the byproduct of a hydrogen fuel cell?
What is the byproduct of a hydrogen fuel cell?
water
Hydrogen can be used in fuel cells to generate power using a chemical reaction rather than combustion, producing only water and heat as byproducts.
What is the by product of hydrogen production?
The downside to this process is that its byproducts are major atmospheric release of CO2, CO and other greenhouse gases. Depending on the quality of the feedstock (natural gas, rich gases, naphtha, etc.), one ton of hydrogen produced will also produce 9 to 12 tons of CO2, a greenhouse gas that may be captured.
What two waste products are produced by hydrogen fuel cells?
Environmental Impact When hydrogen is used to power a fuel cell, the only byproducts are water and heat—no pollutants or greenhouse gases are produced. Even when fossil fuels are used to power a fuel cell the emissions are significantly reduced when compared with conventional fossil fueled generation technologies.
What are the byproducts emissions from a fuel cell?
Fuel Cell – a device that uses hydrogen (or hydrogen-rich fuel) and oxygen to create electricity by an electrochemical process. If pure hydrogen is used as a fuel, fuel cells emit only heat and water as byproducts. 1 Also called a gas battery.
What is the waste product of the use of hydrogen?
When natural gas is burnt, it provides heat energy. But a waste product alongside water is carbon dioxide, which when released into the atmosphere contributes to climate change. When we burn hydrogen, the only waste product is water vapour.
Are there any harmful wastes produced by hydrogen fuel cells?
In addition to financial loss, the waste creates harmful greenhouse gas emissions (GHG) from a variety of sources, including landfill emissions from decaying food, redundant transport energy, and more. Waste is comprised of carbon-rich organic compounds and nutrients that can be used to make biofuels like biogas.
Do fuel cells produce pollution?
Fuel cells do not emit any pollution at their point of use when run on pure hydrogen. The “well-to-wheels” emissions of fuel cell electric vehicles running on renewable hydrogen (extracted from water using clean energy) are almost 100 percent lower than those of conventional gasoline vehicles.
What is the waste product exhausted from a fuel cell electric vehicle FCV )?
Fuel cells have several advantages: they are quiet, produce only water as a waste product, extract electricity from fuel more efficiently than combustion-boiler-generator systems. As early as 1900, scientists and engineers were predicting that fuel cells would be the primary source of electric power within a few years.
What are three uses of hydrogen?
Use of hydrogen. Nearly all of the hydrogen consumed in the United States is used by industry for refining petroleum, treating metals, producing fertilizer, and processing foods.
What are 5 things hydrogen is used for?
Other examples of hydrogen use include rocket fuel, welding, producing hydrochloric acid, reducing metallic ores and filling balloons, according to Los Alamos.
What are the most promising uses for hydrogen fuel cells?
Automotive Applications. One of the most promising uses of hydrogen fuel cells is in the automotive industry.
How do you put hydrogen in a fuel cell?
Hydrogen is forced into the fuel cell at the anode in the form of H2 molecules, each of which contains two hydrogen atoms. A catalyst at the anode breaks the molecules into hydrogen ions (the protons) and a flow of electricity (the electrons). The ions pass through the membrane, but the electricity has to go around.
Are there any waste products of hydrogen fuel cells?
One waste product of hydrogen fuel is water. Some sources say that the other waste product is carbon dioxide or nitrogen oxide. This is potentially a harmful waste product in large quantities. When used in a fuel cell, carbon produces no emissions.
What are the uses of hydrogen fuel cells?
Hydrogen fuel cells generate electricity from oxygen and hydrogen. These electrochemical cells generate only water vapor so it is considered as environment friendly. Fuel cells are used in spacecrafts, remote weather stations and submarines. When in liquid form, it is used as rocket fuel.
